Compute: {{MATH_87}} {{CMD_88}} We find the form of this limit by looking at the limits of the numerator and denominator separately. The limit of the numerator is: {{ENV_89}} The limit of the denominator is: {{MATH_90}} Our limit is therefore of the form {{CMD_91}}{{CMD_92}}and we can probably factor a term going to {{MATH_93}} out of both the numerator and denominator. {{MATH_94}} When looking at the denominator, we hope that this term is {{MATH_95}}. Unfortunately, it is not immediately obvious how to factor an {{MATH_96}} out of the numerator. So, we should first simplify the complex fraction by multiplying it by {{MATH_97}} this will allow us to cancel immediately {{ENV_98}}
