I am having problems understanding this. Could someone explain how to arrive at the answer for this problem . (-5/2)(x)(x+3)^(-3/2) + (5)(x+3)^(-1/2) Thank you It says to factor and simplify. Express the answer as a fraction without negative exponents. This is where I get to (-5x/2)(1/cubed root of (x+3)^3) + 5 / (cubed root of x+3 ) edit here is more i got -5x/2(x+3)^2) + 5/(x+3) get common denominator times the second by x+3 then by 2 so -5x/2(x+3)^2 + 10x + 30 / 2(x+3)^2 I assume I have to get a common denominator but I am unsure of how to do that with negative fraction exponents that are not already equal.
