Answer 4

solve for x then use your x you found to evaluate log_2(x/4)

Answer 5

I just started learning this, can you explain it to me?

Answer 6

\[\log_a(x)=y \text{ \implies } a^y=x\]

Answer 7

\[\log_{4} x=12,4^{12=x}\]
\[\log_{2} \frac{ x }{ 4 }=\log_{2} \frac{ 4^{12} }{ 4 }=\log_{2} 4^{11}=\log_{2} \left( 2^2 \right)^{11}\]
i think now you can complete.

Answer 8

so you try solving
\[\log_4(x)=12\]

Answer 9

ok nevermind

Answer 10

I'm completely lost.

Answer 11
