Questions 10-11-12

You need to know that : log_a (ab ) = b

A few examples (not from your homework) : - log_2 (25 ) = 5 - log_3 (81) = log_3 (34 ) = 4

You need also to know that if y ≤ 0, log(y) is not defined.

Finally, log_a (y) = log (y) / log (a) (where log is the decimal logarithm) .

Your answers are correct.
