solve 2^(x+3) =4^x?

OpenStudy (anonymous):

hint: 4^x = 2^(2x)

OpenStudy (anonymous):

I think you should Distribute the first equation but from there I cant help anymore :)

OpenStudy (anonymous):

\[2^{(x+3)} =4^x \rightarrow 2^{(x+3)} =2^{2x} \]

OpenStudy (anonymous):

is the answer x=3?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

yes .. you can show your solution here

OpenStudy (anonymous):

Now since bases on both sides are same, therefore we can equate the powers on both sides so \[(x+3) =2x \rightarrow 3 = 2x-x \rightarrow x=3\]

yes! thank you all :)
