SOLUTION: Use properties of rational exponents to simplify each expression. Assume that all variables represent positive numbers. a.)(-125)^(-2/3) this would be (1/25) b) (8m^5)^(1/2

Question 886467: Use properties of rational exponents to simplify each expression. Assume that all variables represent positive numbers.
a.)(-125)^(-2/3)
this would be (1/25)
b) (8m^5)^(1/2) over m(7/6)
would this be 2m^(4/3){sqrt(2)}
Im not sure if these are correct. Thanks for the help!
