Question 881776: Good evening,
I am trying to solve this particular problem 3^x=25. I started off with doing the whole process of log base of 3 (25)=x, but I get stuck after I turn 25 into its exponential form and I do not know what to do with 3^x. Someone please help me on this topic. Thank you in advance.

You can put this solution on YOUR website!
Once you get to x+=+log%283%2C%2825%29%29, you are finished because you have isolated x.

You can use the change of base rule to get

x+=+log%283%2C%2825%29%29

x+=+log%28%2825%29%29%2Flog%28%283%29%29

x+=+2.92994704143586 Use a calculator here. This value is approximate.
