Answer:

(tenth root of x to the third power)

see image

Explanation:

To do this problem you need to know how to convert radicals to an expression with a fraction exponent(and back to radicals again), ALSO exponent rules for division ALSO subtracting fractions.

Square root x can be written as x^ 1/2

fifth root x can be written as x^ 1/5

When you are dividing expressions with the same base, exponent rules say to SUBTRACT the exponents.

1/2 - 1/5 change to common denominator

5/10 - 2/10

= 3/10

x^1/2 / x^1/5 =

x^ (1/2 - 1/5) =

x^ (5/10-2/10) =

x^ 3/10

Then change back to a radical. Remember "down and out" or "roots are down" and "up, up, up" or "exponents are up"

the number down below goes out (outside) the radical. And the number up top is up and exponents are up, up, up

see image.

x^3/10 =

tenth root (x^3)
