 Question 31245: Please help my homework is due today -3(-4x^-6)-2 and also x^7y^-4 _________ -2x^-2 and all has large bracket around entire problem and ^of -3Answer by troyapplehelen(46)   (Show Source): You can put this solution on YOUR website!in second problem, y^(-4) is 1/y^4 or bring it down to the denominator as y^4. also, x^(-2) is 1/x^2 or bring it up to the numerator as x^2. then rewrite it as {(x^7)(x^2)}/-2(y^4). and the powering with -3, is (positive 3rd power) of its reciprocal. so, [{-2(y^4)}^3]/(x^9)^3
