As we have learned

Limit of power -

\lim_{x\rightarrow a}f(x)^{g(x)}=(P)\lim_{x\rightarrow a}g(x)


Where\:f(x)^{g(x)}\:does\:not\;take\:indeterminate\:form\:at\:x=a

- wherein

Where P is a non zero finite constant

 

 When x\rightarrow 2 then (2x-1)\rightarrow 3  and \frac{x+4}{x+1}(2x+1)^{\frac{x+4}{x+1}}= 3^{2}=9
