Solve 4^x = 12

OpenStudy (anonymous):

x=12/4 x=3

OpenStudy (anonymous):

yyup its 3

OpenStudy (anonymous):

are you sure its not one of my answers. maybe i wrote it in wrong..my choices are x ≈ 0.27 x ≈ 0.56 x ≈ 1.79 x ≈ 19.93

OpenStudy (anonymous):

take log4 of both sides to get the x out of the exponent \[x=\log_{4}12\]

OpenStudy (anonymous):

ok so do i have to find the in for 12 after i do that?

OpenStudy (anonymous):

Just type the answer into a calculator and it will give you a decimal

OpenStudy (anonymous):

ok thankyou

OpenStudy (kropot72):

\[4^{x}=12\] Take logs of both sides: \[x \log_{} 4=\log_{} 12\] \[x=\frac{\log_{} 12}{\log_{} 4}=?\]
