Need help on this!! 10 points!!

Answer 1

Answer:

Step-by-step explanation:

The change of base formula is

$log_a(b)=\frac{log_{10}b}{log_{10}a}$ so filling in our given:

$log_{13}}(297)=\frac{log_{10}297}{log_{10}13}$ (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

$\frac{log297}{log13}=2.2198$ Not sure how many decimal places you needed!
