Question

Use logs to solve for X to the nearest hundredth:
4(9^x)=160

Answer 1

\[4\times 9^x=160\]divide by 4
\[9^x=40\]
then use \(b^x=A\iff x=\frac{\ln(A)}{\ln(b)}\)

Answer 2

in your case \(x=\frac{\ln(40)}{\ln(9)}\) then a calculator

Answer 3

ok i got 1.678881391

Answer 4

me too

Answer 5

so 1.678881391 to the nearest hundredth would be 1.68?

Answer 6

yes

Answer 7

THX!!!
