The value of `Lim_(xto0) (5x^(2)+[x^(2)+1])^(((1)/(x^(2)+sin^(2)x)))` is, [Note : [y] denotes greatest interger less than or equal to y.]A. `(5)/(2)`B. `e^((5)/(2))`C. `(25)/(2)`D. `e^((25)/(2))`

Answer» Correct Answer - A
`underset(xto0)Lim(5x^(2)+[x^(2)+1])^(((1)/(x^(2)+sin^(2)x)))=e^(L)`
where `L=underset(xto0)Lim(1)/(x^(2)+sin^(2)x)(5x^(2)+[x^(2)+1]-1)=underset(xto0)Lim(5x^(2))/(x^(2)+sin^(2)x)=(5)/(2)`
`:." Limit"=e^((5)/(2))`.
