Question

cube root of 64 is _
a. 8
b. 4​

Answer 1

Answer: b) 4

Step-by-step explanation:

Let cube root be x.

Then $x^{3\\}$ = 64

         x = $\sqrt[3]{64}$

         x = $\sqrt[3]{2*2*2*2*2*2}$

         x=  2 * 2

         x= 4

           

To verify :

4*4*4 = 64

Hence answer is correct.

Hope it helps!
