Question

4^x=12

Answer 1

\[b^x=A\iff x=\frac{\ln(A)}{\ln(b)}\]

Answer 2

this is sometimes called the "change of base" formula
in your case \(A=12,b=4\)

Answer 3

Log both sides so u get log 4^x =log 12. therefore by law of logs x log 4 = log 12. so x=log 12/log 4...

Answer 4

thank you so much

Answer 5

\[\log 4^{x} = \log 12\]
\[x \log 4 = \log 12 \]
\[x = \log 12\div \log 4 \]
