Hello again..

Alright I am now on the part of 12th grade calculus, dealing with logs and exponents and stuff. I understand if say log39 That its basically what power do you raise 3 to to get 9. Well a question i need to answer is log162. So what power to I raise 16 to to get 2? I used my calculator just trying to find a number that would work, and i got 0.25. How would I show work for that? all of the solutions they gave for different equations worked different like for the log39They showed 2 ways:

3^x=9

3^x=3^2

x=2

OR

log39=log3(3^2)

=2

None of these solutions work for 16 since 2 is 2^1 and 16^1 is 16 not 2... I am confused.. Is 0.25 even the right answer.

Any Help is appreciated greatly!

Thanks ya!
