1) An expression that occurs in calculus in given. Reduce the expression to lowest terms.
(2x + 5) 4x - 2x^2(2) / (2x+5)^2
I have no idea what to do for this.
2) Simplify the expression. Express the answer so that only positive exponents occur. Assume that all variables are positive.
(-3 x^4/7) ^4 / x^-1/2
I know that (-3)^4 would be 81 but I do not know what else to do.
