Question

What is the solution to the equation 7^–3x ≈ 9 ?

Answer 1

\[-3x=\frac{ln(9)}{\ln(7)}\] is the first step

Answer 2

oh I see so after doing ln(9)/ln(7) I'd set it equal to -3x and solve from there?

Answer 3

@satellite73

Answer 4

\[\frac{\ln(9)}{\ln(7)}\] is a number
solve \[-3x=\frac{\ln(9)}{\ln(7)}\] by
\[x=-\frac{\ln(9)}{3\ln(7)}\]
