Question

Given that a^b=x, evaluate the following: a^2b

Answer 1

`a^(2b)=x^(2)`

Explanation:

we know that

`a^(b)=x` ----> equation A

Find the value of
`a^(2b)`

Remember that

`a^(2b)=(a^(b))^(2)`

`(a^(b))^(2)` ----> equation B

substitute equation A in the equation B

`(a^(b))^(2)=x^(2)`

therefore

`a^(2b)=x^(2)`
