Question

64^4x=16^x+4 Please Help!

Answer 1

\[64^4x=16^{x+4}\]
is that it?

Answer 2

no i mean\[64^{4x}=16^{x+4}\]

Answer 3

divide both sides by 16^x+4:
\[4^{10x-8}=1\]

Answer 4

take log base 4 of both sides so you get:
\[10x-8=0\]
and now you can solve it by yourself

Answer 5

you can also solve it by writing it as :
\[4^{3*4x}=4^{2(x+4)}\]
then:
\[3*4x=2(x+4)\]
and solved as normal

Answer 6

Thanks a bunch I was stuck on that one for awhile
