Answer 2

The cube root of 512 is 8

Explanation:

The cube root of a number is expressed in radical form as;

`\sqrt[3]{x}`

Using exponents, the above expression is equivalent to;

`x^{(1)/(3)}`

512 can be expressed as;

2*2*2*2*2*2*2*2*2

This is equivalent to;

`2^(9)`

Therefore;

`512^{(1)/(3) }=(2^(9))^{(1)/(3) }=2^(3)=8`

The cube root of 512 is thus 8
