Question

Simplify: (-h^4)^5

Would it be -h^20 or h^20

Answer 1

+ h^20

Explanation :

[(x)^a]^b = (x)^(a)(b) = (x)^ab

But Be Careful when it's like

[ (x)^(1/2) ] ^2

where (^1/2) is the square root and you can't put a negative value under a square root

Answer 2

Addition

But When it's

[ (x)^2 ] ^1/2

you can put a negative value under the square in this case

besides that you change the powers
ex :

(-8)^2/3

that means [ (-8)^2 ] ^1/3
and you can write it as [ (-8)^1/3 ] ^2

* for (^1/3) you can put a negative value

the answer in both cases is 4
first you take the third root of -8 = -2
and the square of -2 = 4


sorry for the long answer but i wanted to make it clear to you

Answer 3

Thank you so much for taking the time to explain it.
