Cube Root of 50
We will learn the cube root concept to use it on other mathematical topics like algebra, mensuration, geometry, trigonometry, etc. So, it is as important as learning square roots. Let us now see how we can obtain the cube root value of 50, and its examples.
What Is the Cube Root of 50?
The cube root of 50 is the value which, when multiplied by itself three times (cubed), gives the original number 50. The cube root of 50 is 3.68403149864. The cube root of, 50 is expressed as β50 in radical form, where the “ β ” sign” is called the “radical” sign. In exponential form, it is written as (50)β
. If “m” is the cube root of 50, then, m3=50. Let us find the value of “m”.
Finding the Cubic Root of 50
We can find cube roots of 50 through a method, named as, Halley’s Method. Let us see how it finds the result.
Cubic Root of 50 By Halleyβs Method
Now, what is Halley’s Method? It is an iterative method for finding cube roots of a given number N, such that, x3=N, where this method approximates the value of “x”.
Formula is βa≅ x((x3+2a) / (2x3+a)), where
a=given number whose cube root you are going to find
x=integer guess for the cubic root
Let us apply Halley’s method on the given number, 50.
Step 1: Let a=50. Let us take x as 3, since 33=27 is the nearest perfect cube which is less than 50.
Step 2: Apply the formula. β50≅ 3((33+2×50) / (2(3)3+50)) = 3.66…
Hence, 3.66… is the approximate cubic root of 50.
Common Mistakes and How to Avoid Them in the Cube Root of 50
Understanding common misconceptions or mistakes can make your calculations error free. So let us see how to avoid those from happening.
Mistake 1
For β50, students can make error in the important part of prime factorization.
Prime Factorization is a crucial part in determining cube roots and square roots. So, use the exact prime factors and group (or pair).
Mistake 2
Applying exponent rules incorrectly when finding cube roots
β50 is not same as 50 . β50 = 3.66… and, 503 is 125000.
Mistake 3
For large non-perfect cubes, students frequently estimate wrongly and leave it with a wrong result.
Keep the methods of finding cube roots in front whenever attempting large non-perfect cubes.
Mistake 4
Students typically rely on memorizing rather than understanding concepts of cube root.
Memorizing is not the solution when it comes to complex problems. So understanding the methods of finding cube roots is advisable.
Mistake 5
Misapply the cube root property like when asked to solve β(50)3, students might do as β(50×3)
Clear the concepts again and again if they don’t understand, where to do what. β(50)3≠β(50×3). β(50)3= 50
Cube Root of 50 Examples
Problem 1
Find ((β150/ β50) Γ (β150/ β50) Γ (β150/ β50))
(β150/ β50) × (β150/ β50) × (β150/ β50)
= (β150× β150× β150) / (β50× β50× β50)
=((150)β
)3/ ((50)β
)3
=150/50
=3
Answer: 3
Explanation
We solved and simplified the exponent part first using the fact that, β150=(150)β
and β50=(50)β
, then solved.
Problem 2
If y = β50, find (yΒ³/ yβΆ)Γ(yΒ²/yβ΄)ΓyΒ³
: y=β50
⇒ (y3/ y6)×(y2/y4)
= ((β50)3 / (β50)6)×((β50)2 / (β50)4)× (β50)3
⇒ (y3/ y6)×(y2/y4)= (50/ (50)2) × (502/3-4/3)×(50)= 1/(50)2/3
Answer:1/(50)2/3
Explanation
(β50)3=(501/3)3=50, β(50)6=(501/3)6=(50)2, (β50)2=(501/3)2=502/3, and (β50)4=(501/3)4=(50)4/3 Using this, we found the value of (y3/ y6)×(y2/y4)×y3.
Problem 3
Multiply β50 Γ β1000 Γ β125
β50 × β1000 × β125
= 3.66 × 10 ×5
= 183
Answer: 183
Explanation
We know that the cubic root of 1000 is 10 and the cubic root of 125 is 5, hence multiplying β125, β1000 and β50.
Problem 4
What is β(10)βΆ + β(50)βΆ?
β(106)+ β(50)6
= ((10)6))1/3 +((50)6)1/3
=(10)2 + (50)2
= 100 + 2500
Answer: 2600
Explanation
We solved and simplified the exponent part first using the fact that, β10=(10)β
and β50=(50)β
, then solved.

Important Glossaries for Cube Root of 50
- Cube root properties - The features when cube root is applied to any number. Those are: 1) The cube root of all odd numbers is an odd number. The same applies for even numbers also, that is, the cube of any even number is even.
2) The cube root of a negative number is also negative.
3) If the cube root of a number is a whole number, then that original number is said to be perfect cube
- Irrational Numbers - Numbers which cannot be expressed as m/n form, where m and n are integers and n not equal to 0, are called Irrational numbers.
- Square root -The square root of a number is a number which when multiplied by itself produces the original number, whose square root is to be found out.
- Polynomial - It is an algebraic expression made up of variables like “x” and constants, combined using addition, subtraction, multiplication, or division, where the variables are raised to whole number exponents.
- Approximation - Finding out a value which is near to the correct answer, but not perfectly correct.
- Iterative method - This method is a mathematical process which uses an initial value to generate a further sequence of solutions for a problem, step-by-step.
