Professor Greenline Explaining Math Concepts

To simplify complex calculations, we convert the logarithmic expression into exponential form. For example, log_aN = x can be written in exponential form as a^x = N. In this article, we will learn about the logarithmic to exponential form, its formulas, and solved examples.

Log to Exponential Form for UK Students

What is Log to Exponential Form?

Logarithmic expressions can be converted into exponential form using the log to exponential rule. It helps solve equations more easily. We use it to simplify the calculation of very large numbers, especially in scientific and engineering contexts. The log to exponential form is based on the principle that if log_aN = x, then in exponential form it can be written as a^x = N.

What are the Formulas for Log to Exponential Form?

There are specific formulas related to both logarithms and exponents in the log to exponential form. Logarithms simplify multiplication and division by converting them into addition and subtraction. Exponential forms help efficiently handle expressions involving powers and different bases. We will learn the log and exponential formulas in the next sections.

What are the Formulas for Log?

When working with complex logarithmic expressions, we use the logarithmic properties. These properties simplify complex expressions involving multiplication, division, and exponents by converting them to simpler operations. The formulas for logs are:

log (ab) = log a + log b
log (a/b) = log a - log b
log_b a = (log a)/(log b)
log a^x = x log a
log₁ a = 0
log_a a = 1
d/dx ∙ log x = 1/x

What are the Formulas for Exponential?

The exponential formula is used to express repeated multiplication of the same number in a simplified formula. We convert the exponential forms to logarithmic forms to simplify the calculations. The formulas for exponentials are:

a^p= a × a × a × …… p times
a^p ∙ a^q = ap + q
a^p/a^q = a^{p - q}
(ap)q =apq
ap ∙ bp = (ab)p
a⁰ = 1
a¹ = a
a^-1 = 1/a

Real-world applications of Log to Exponential Form

By learning how to convert log to exponential form, we can solve problems related to population growth, earthquake intensity, sound levels, and many more. Here are some applications of log to exponential form.

The Richter scale is used to measure the intensities of earthquakes. We use the logarithmic formula: M = log₁₀ (I/I₀).

In biology, we often follow an exponential model to study bacterial growth:
N(t) = N₀e^rt.

To study the population growth using the model population, we use the exponential and logarithmic forms. To analyze or predict the population trends over time.

Common Mistakes and How to Avoid Them in Log to Exponential Form

When converting log to exponential form, it is important to memorize the formulas. Many students find this conversion difficult and make mistakes. Here are some common mistakes and the ways to avoid them.

Mistake 1

Confusing base and results

Mostly, students make mistakes in assigning base, exponent and result.

For example, converting log₂8 = 3 to exponential form, students write it as 2 = 8³ instead of 2³ = 8. To avoid the error, always remember that log_a N = x in exponential form is: a^x = N.

Mistake 2

Forgetting to add the base in the exponent form

Students forget to add the base in the exponential form;

For example, students write log₂8 = 3 in exponential form as 3 = 8, which is wrong. As they forget to add the base, the logarithmic expression in exponential form should be written as 2³ = 8.

Mistake 3

Misunderstanding the role of the exponent

Students apply the exponent as a multiplier instead of exponentiation.

For example, when solving log₃ (9) = 2,

3 × 2 = 6 instead of 9. The correct way of solving is:

log₃ (9) = 2 ⇒ 3² = 9

So, always use exponentiation instead of multiplication.

Mistake 4

Incorrectly arranging the equation

Students sometimes confuse the base, exponents, and the results, which results in the wrong arrangement of the equation.

For example, converting log₂ (64) = 6 as 16 = 6² or 4 = 64⁴ instead of 2⁶ = 64. To avoid these errors, always remember the format that is log_a b = c ⇒ a^c = b.

Mistake 5

Errors when converting log equal to zero to exponential form

Misapplying the logarithmic rule is common among students; in exponential form, log_b (1) = 0 is written as 1⁰ = 0, which is wrong, as it should be b⁰ = 1. Use the standard structure when converting a log to exponential form, that is: log_a x = y ⇒ a^y= x

Solved Examples of Log to Exponential Form

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

Convert log_2 8 = 3 to exponential form

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

2³ = 8

Explanation

The log form of log_a N = x, in exponential form, it is equal to a^x = N

In log₂ (8) = 3, a = 2 and x = 3

So, a^x = N ⇒ 2³ = 8

Problem 2

Find the value of log⁡ 32, given that log_10⁡ 2 = 0.301

The value of log 32 is 1.505

Explanation

Given, log 2 = 0.301

32 can be written as 2⁵

So, log 32 = log (2)⁵

= 5 log 2

= 5 × 0.301

= 1.505

Problem 3

Convert log_2 32 = 5 to exponential form

2⁵ = 32

Explanation

To convert the log form to exponential form, we use:

log_a x = y ⇒ a^y = x

Here, a = 2 and y = 5

2⁵ = 32

Problem 4

Convert log_6 36 = 2 to exponential form

6² = 36

Explanation

We use log_a x = y ⇒ a^y = x to convert a log to exponential form

Here, a = 6 and y = 2

So, in exponential form it is written as: 6² = 36

Problem 5

Find the value of log⁡ 200, given that log⁡ 2 = 0.301 and log⁡ 5 = 0.699.

The value of log 200 is 2.301

Explanation

Given,

log 2 = 0.301

log 5 = 0.699

200 can be expressed as 2³ × 5²

So, log 200 = log(2³ × 5²)

= 3 log 2 + 2 log 5

= 3 × 0.301 + 2 × 0.699

= 0.903 + 1.398

= 2.301
