+ 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
Simplify: (-h^4)^5
Would it be -h^20 or h^20

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
