Question

Q.15 Cube root of 8 is:A) 4 B) 2 C) 3 D) 12.​

Answer 1

Answer:

Cube root of 8 is 2

Step-by-step explanation:

we can express 8 as 2 × 2 × 2

i.e.

∛8 = ∛(2 × 2 × 2) = 2. Therefore, the value of the cube root of 8 is 2.

Answer 2

As per the data given in the question,

We have to determine the value of cube of 8.

As we know that,

Cube of any number can be determined by multiplying the given number by itself thrice.

Like if we have to determine cube of 1 then we have to multiply 1 by itself thrice.

So,

Cube root of the 8 will be,

$8^{\frac{1}{3}}\\=>2^3^{\frac{1}{3}}\\=>8^{\frac{1}{3}} = 2$

Hence, value of cube root of 8 will be 2.
