There is a standard trick for dealing with the indeterminate forms {{MATH_172}} Given {{MATH_173}} and {{MATH_174}} such that {{MATH_175}} falls into one of the categories described above, rewrite as {{MATH_176}} and then we rewrite as {{MATH_177}} Recall that the exponential function is continuous. Therefore {{MATH_178}} Now we will focus on the limit {{MATH_179}} using L'H{{CMD_180}}pital's rule. (After calculating this limit, don't forget to plug back into the exponential.)
