Question

Need help on this!! 10 points!!

Answer 1

Explanation:

The change of base formula is

`log_a(b)=(log_(10)b)/(log_(10)a)` so filling in our given:

`log_(13)}(297)=(log_(10)297)/(log_(10)13)` (Note: you do not have to put the base of 10 in the change of base formula because the "normal" base for a log is 10 and that is how your calculator figures it.)

Do this on your calculator to get

`(log297)/(log13)=2.2198` Not sure how many decimal places you needed!
