In the last two examples below, notice that they are different exponential indeterminate forms, but we approach them with the same
technique.
{{CMD_181}}
First determine the form of the limit, then compute the limit.
{{MATH_182}}
Select the correct choice. The form of the limit is
{{CMD_183}}
{{CMD_184}}{{MATH_185}}{{CMD_186}}
{{CMD_187}} {{CMD_188}}{{CMD_189}}
{{CMD_190}}{{MATH_191}}{{CMD_192}}
{{CMD_193}} {{CMD_194}}{{CMD_195}}
{{CMD_196}}{{MATH_197}}{{CMD_198}}
{{CMD_199}}{{MATH_200}}{{CMD_201}}
{{CMD_202}}{{MATH_203}}{{CMD_204}}
{{CMD_205}}
{{CMD_206}}
Write
{{MATH_207}}
Now we look at the limit in the exponent.
{{MATH_208}}
Since {{MATH_209}} and {{MATH_210}}, we know that
{{MATH_211}} has form {{MATH_212}}, so we can apply l'H{{CMD_213}}pital's Rule.
That gives:
{{ENV_214}}
Notice that {{MATH_215}} had form {{MATH_216}}, we used l'H{{CMD_217}}pital's Rule again
in that step.
Remember that {{MATH_218}}. We just calculated that
{{MATH_219}}, which means:
{{MATH_220}}
{{CMD_221}}
