22 If the base is not indicated then it is assumed to be base 10. Natural logs always use base e. It does not have to be indicated. a..698970 b. -2.302585 21Algebra 2 Honors

23 In order to find the inverse of a log you must first convert it to exponent form. Rewrite as an exponent Switch x and y Solve for y Rewrite as an exponent Switch x and y Solve for y 22Algebra 2 Honors Recall in order to find the inverse you must switch x and y then solve for y.
