Fractional exponents and higher roots are a very weak point for me i will mark u as brainliest.(this is a 2 part questions)

So an easy way to find these is by prime factorization. Factor the number until you can not factor any smaller. Start by dividing by smallest prime numbers like 3 or 2 for even numbers. Then look to find the correct number of roots.

Example : 4th root of 256
256
2*128
2*2*64
2*2*2*32
2*2*2*2*16
(2^4)*16
(2^4)*2*8
(2^4)*2*2*4
(2^4)*2*2*2*2
(2^4)*(2^4)
4th root of 256 = 2 × 2 = 4
Since it's an even power answer will be positive or negative. +4 or -4

A root is written as fraction power. So square root is to the power of 1/2 to the 7th power  is 7*1/2 = 7/2

32^(3/5) = [32^(1/5)]^3

2^5 = 32
you can see this by prime factoring..
32
2*16
2*2*8
2*2*2*4
2*2*2*2*2
So the 5th root of 32 is 2
Then
2^3 = 8
