Best ResponseYou've already chosen the best response.0These were the choices i was given x = negative 21 over 2 x = 6 x = negative 6 over 5 x = 12

Best ResponseYou've already chosen the best response.0Does this happen to be from a lesson called "Solve Exponential Equations" ?

Best ResponseYou've already chosen the best response.0Okay.. Uhm.. I've never seen one with a square root but let me see if I can solve it then I'll show you

Best ResponseYou've already chosen the best response.0\[\large \sqrt{(7)}^{6x}=49^{x6}\]\[\large (\sqrt{7})^{6x} = \color{green}{(\sqrt{7})^{4(x6)}}\]\[\large 6x = 4(x6)\]\[\large 6x=4x24\] solve for x.

Best ResponseYou've already chosen the best response.0i changed it to the sae base.\(\sqrt{7}^4\)=49. and you've gotthe base \(\sqrt{7}\) on the left side.

Best ResponseYou've already chosen the best response.0Tell me how you changed \(\large (\sqrt{7})^{6x}\) to just 7?

Best ResponseYou've already chosen the best response.0I just figured because you square it. I've never done one like this. I was going out on a limb. But you are are correct because qroot7^4 is 49.

Best ResponseYou've already chosen the best response.0So in that case it's 12 and not 6/5.

Best ResponseYou've already chosen the best response.0I just put 7^2 because I knew you have to have like the same "base number" Or whatever.

Best ResponseYou've already chosen the best response.0That 's if you want to use 7 and not sqrt(7)

Best ResponseYou've already chosen the best response.0\[\large (\sqrt{7})^4 = 7^{4/2} = 7^2 \]

Best ResponseYou've already chosen the best response.0Yeah....same thing.
