SOLUTION: Rewrite each expression using rational exponents. Assume that all variables represent positive numbers. [sqrt(x^5)} =x^(5/2) (cube root of 7xy)^4 =7^(5/3)x(4/3)y(4/3)

Question 886465: Rewrite each expression using rational exponents. Assume that all variables represent positive numbers.
[sqrt(x^5)}
=x^(5/2)

(cube root of 7xy)^4
=7^(5/3)x(4/3)y(4/3)
Are these right? Im not positive. Thanks for the help!
