Question

Solving exponential functions: 8x=12,143

Answer 1

I'm not sure where to start.

Answer 2

I got 0

Answer 3

can you show me how you did it please?

Answer 4

No its not 0

Answer 5

so the question is

\[8^x = 12143\]

Answer 6

if it is... take the log of both sides

\[\ln(8^x) = \ln(12143)\]

using log laws it can be written as

\[xln(8) = \ln(12143)\]

so

\[x = \frac{\ln(12143)}{\ln(8)}\]

just evaluate for the solution.
