Best ResponseYou've already chosen the best response.0Here you apply three functions to x [5*•, •2, ln •] and want a point x with a certain function value. Luckily all these functions are injective (onetoone, monomorphisms). So you can simply apply the inverse functions in inverse order to 12, so first the inverse of ln, which is exp, then the inverse function of •2 and then the inverse function of 5*•.

Best ResponseYou've already chosen the best response.0\[ln(5x2) = 12\] \[\implies 5x2 = e^{12}\] And continue to solve for x.

Best ResponseYou've already chosen the best response.0Remember that \[e^{ln\ a}=a\] So were just raising e to the power of each side of the equation to remove the natural log function.
