Thread: Basic Log Problem

Use logarithms to solve the equation for x. [Hint: take logs of both sides and simplify]

10x=y Okay So I'm Lost because for my final answer I got log(y) and it did not accept my answer, either I'm doing the problem wrong or I'm right and it might be just a glitch. So please help! la

What are you asking?
If 10x = y, then x = y/10

Why bring in logs?

I typed it wrong. It's suppose to be 10^x=y and you're suppose to solve x by using logs to both sides.

$10^x = y$

$\log_{10}(10^x) = \log_{10}(y)$

$x = \log_{10}(y)$
