Question

What integer is equal to 8^ 2/3 ?

Answer 1

Simplifying it, convert it to a radical form, and evaluate it.. Either way it all equals to a simple whole number, which is '4',

well, except when you convert the expression to radical form using the formula 'a^x/n=n√a^x' then it'll be '^3√8^2'.

Answer 2

4

Explanation:

8 ^ (2/3)

The 2 means squared and the 3 means root

8^2 ^ (1/3)

Rewriting 8 as 2^3

2^3 ^ (2/3)

We know a^ b^c = a^ (b*c)

2 ^ (3*2/3)

2^ 2

4

OR

8 ^ (2/3)

The 2 means squared and the 3 means root

8^2 ^ (1/3)

64 ^ 1/3

We know 4*4*4 = 64

(4*4*4)^ 1/3
