need help Solve 8 = 2^x+4

OpenStudy (anonymous):

First, subtract both sides by 4, what will you get?

OpenStudy (anonymous):

the x+4 is above the 2, do I still do that?

OpenStudy (anonymous):

oh I see.. so it's like \(\sf 8 = 2^{x+4}\) ?

OpenStudy (anonymous):

if yes, then no. The thing you have to do is change 8 into base 2

OpenStudy (anonymous):

how many times do you have to multiply 2 by itself to get 8?

OpenStudy (anonymous):

4

OpenStudy (anonymous):

really? 2 x 2 x 2 x 2 is 16 not 8

OpenStudy (anonymous):

I got it thank you so much again (:

OpenStudy (anonymous):

O_o? lol we haven't done anything yet

OpenStudy (anonymous):

OpenStudy (anonymous):
