√(5 & x^4 )

Is really just another way of saying

(5 & x^4 )^0.5

because anything to the 1/2 or 0.5 power is the same as taking the square root.

a fractional exponent means instead of placing roots you would use powers so the square root would be (1/2)

if it were the cube root then it would be (1/3)

if you have a/b the bottom is the number on the root so for this one its two the top would be the amount of times you multiply it to each other.

SO (5X^4)^1/2

i assume the & is a multiplication sign?? if that's the case, then its:

5^1/2&x^4/2

which equals

5^1/2&x^2

the top # is the power its too while under the radical, the bottom # is the number root you are taking
