Best ResponseYou've already chosen the best response.0Reason I'm confused is because unlike log, in ln the exponential form is e^y=x and I'm having trouble solving the rest

Best ResponseYou've already chosen the best response.0yep. now, ln(0) = 1 because e^0 = 1

Best ResponseYou've already chosen the best response.0use quadractic formula x=(9@sqrt(814(1)(20e))/2 where @ means + or , but make sure your answer is positive because you cannot do ln(negative)

Best ResponseYou've already chosen the best response.0(1+sqrt(14(20e))/2=4.2925 and (1sqrt(14(20e))/2=5.2925 but we can't use 5.2925 since it is negative and the natural log of a negative number doesnt exist

Best ResponseYou've already chosen the best response.0x can be negative if it is not the only thing controling the value of the log. the thing is: x4 needs to be greater than 0 and, x+5 needs to be greater than 0. x >4 serves both cases.

Best ResponseYou've already chosen the best response.0that negative number gives you another negative number when you plug it into x4
