this can probably help u.

Answer 2

I already watched it and I still didn't understand

Answer 3

o. give me a second

Answer 4

8th root 4d^3 (I think this is the third choice you listed?) In front of the radical there would be a little 8, under the radical 4d, and the to the third power. When an exponent is a fraction, put the denominator in front of the radical and the numerator after (as an exponent). For example 2^(1/3) would just equal the cubic root of 2. (2^1=2)
hope this helps.

Answer 5

But does the whole number affect the answer? or is it the same if it were the variable alone?

Answer 6

I think its the same variable alone

Answer 7

so you don't have to move the whole number to the index also?

Answer 8
