Best ResponseYou've already chosen the best response.0Now remember this rule: LnA^b = b*LnA, so apply it here: (x+2)*Ln5 = (x3)*Ln7

Best ResponseYou've already chosen the best response.0move terms with x to one side and the ones without to the other side: xLn5xLn7 = 3Ln72Ln5 Take x out from the left: x(Ln5Ln7) = 3Ln7  2Ln5
