उत्तर

By splitting 1.1 and then applying Binomial Theorem, the first few terms of (1.1)10000 can be obtained as

(1.1)10000 = (1 + 0.1)10000

= `1^10000   + 10000C_1  xx  1^9999  (0.1)^1`

= 1 + 10000 x (0.1) + …. = 1001 +…

It is clear that the number (1.1)10000 is greater than 1000.

Hence, (1.1)10000  > 1000
