Question

Solve 125^9x-2=150

Answer 1

Is this it: \[\LARGE 125^{9x} - 2 = 150 \]or
\[\LARGE 125^{9x - 2} = 150 \]?

Answer 2

If it's the first one, add 2 on both sides:
125^(9x) = 152. Take the natural log on both sides:
9x = ln(152)/ln(125)
x = (ln(152)/ln(125))/9 = 0.11, if my arithmetic is correct.
