# Help with an Alevel Logs question Watch

Announcements
1. Hi guys, been stuck on this logs question for a good couple hours as I just can't get my head around it. The question is as follows:
A law uses the formula R=t^n. If values of R=58 and n=-1.2, transpose and evaluate to find t. (answer to 4 dp) Show proof of your answer.
If anyone can help that would be great thanks.

If you take the logs of something to the power (eg t^n) what happens?

It works out to give you the answer as that's what I did in the end. I took logs of both side, brought the power down using rules of logs and after a little rearranging got the answer. Thanks for the help.
