Hi all!

Just wondering whether i could get some help solving this question for "t"? Do you have to put log10 on each side? Step by step if possible would be greatly appreciated.

20(10^0.1t) = 25(10^0.05t)

Cheers

**20(10^0.1t) = 25(10^0.05t)**

I would divide both sides by 20, then divide both sides by .

You can use index laws to simplify your exponents.

Then I would take a log of both sides. - Oct 21st 2008, 02:55 AMProve It
