Best ResponseYou've already chosen the best response.0I would cross out the bases because they are the same right?

Best ResponseYou've already chosen the best response.0The base is 5 instead of 10?

Best ResponseYou've already chosen the best response.2not exactly. Use the hint!

Best ResponseYou've already chosen the best response.0Oh! I would have no 'y' value right?

Best ResponseYou've already chosen the best response.0nope when there is just log then u have to suppose 10 base

Best ResponseYou've already chosen the best response.2actually, the hint applies to any base, so it was not indicated.

Best ResponseYou've already chosen the best response.0Oh ok, so the answer would just be x = 2?

Best ResponseYou've already chosen the best response.0i'm confused do you have to solve for x right ?

Best ResponseYou've already chosen the best response.2Hint: Whenever you solve an equation involving log, you need to substitute back into the equation to reject all roots that make log negative (recall dom log(x)=(0,inf) ).

Best ResponseYou've already chosen the best response.2@Nnesha yes, the solution x=2 is correct for the algebraic part, but not correct for the problem given!

Best ResponseYou've already chosen the best response.0I have to solve for the problem given @Nnesha

Best ResponseYou've already chosen the best response.0Oh ok, so when I plug x=2 into the final product, I get f(2) = (0,inf) which is not solvable so there is no solution

Best ResponseYou've already chosen the best response.2\(log_5(116x)=log_5(1)\) so x=2 is not an admissible solution because log(1) is outside the domain of log.

Best ResponseYou've already chosen the best response.2* 1 is outside the domain of log.
