6. a. Show lim (1 + = = e using the following steps -00 Step 1) Let y = (1 + =) then take the natural log of both sides Step 2) Use algebra to rewrite the expression In(1 + -)" so that it is of the indeterminate form -. Hint In a = rina.Step 3) Apply I'Hopital's rule to show lim In 1 + - =1 : Notice that if In(a) = 1 then a must be e. 7-+00
