The multiplicative inverse of 10^-100 is
(a) 10
(b) 100
(c) 10¹⁰⁰
(d) 10^-100

Solution:

The Correct answer is (c).

Themultiplicative inverse of a number is defined as a number which when multiplied by the original number gives the product as 1. The multiplicative inverse of 'a' is denoted by a-1 or 1/a. The multiplicative inverse property says that the product of a number and its multiplicative inverse is 1.

Here, multiplicative inverse of 10^-100 is 1/10^-100 = 10¹⁰⁰
