To make it easy you can take the of both sides and use and you can also use in the first place
so would it be 9x/3 log 9 = 8x/2 log 4 ?
If you use the rule I suggested then you get:
ohh!!! ah oki i gotcha now all the rules of exponents just confuse me! thanks so much! do you mind taking a look at my half life problem i posted earlier?
You're welcome! To solve exponential equations then you really have to know this basic rules.
