log 9^x=log 3

by using power rule

xlog9=log 3

divided log 9 on both side

x=log3/log9

press in the calculator

x=0.5

or without using log rule, u could also solve in another way

9=3^2

3^2x=3^1

now u have the same base in bothside (3)

2x=1

x=1/2=0.5

If you keep posting all of your math homework here, and getting other people to do it for you, that’s a clear sign that you either need extra help in math or you need help because you’re not able to appropriately manage your time to allow you time to do your math homework yourself.
