MCQ
The positive integer just greater than $(1 + 0.0001)^{10000}$ is
  • A
    $4$
  • B
    $5$
  • C
    $2$
  • $3$

Answer

Correct option: D.
$3$
d
(d) We know that $e = \mathop {\lim }\limits_{n \to \infty } \,{\left( {1 + \frac{1}{n}} \right)^n}$ and $2 < e < 3$.

 ${(1 + 0.0001)^{10000}} < 3$ (By putting $n = 10000$)

Also ${(1 + 0.0001)^{10000}} = 1 + 10000 \times {10^{ - 4}}+ \frac{{10000 \times 9999}}{{2!}} \times {10^{ - 8}} + ......$upto $10001$ terms 

$ \Rightarrow {(1 + 0.0001)^{10000}} > 2$. 

Hence $3$ is the positive integer just greater than ${(1 + 0.0001)^{10000}} > 2$

Hence $(d)$ is the correct option.
