Ans. A number’s multiplicative inverse is defined as a number that produces 1 when multiplied by the original number. a-1 or 1a denotes the multiplicative inverse of ‘a.’ In other terms, multiplicative inverses are multiplicative inverses of each other when the product of two numbers is 1. The multiplicative inverse of a number is a reciprocal of a number.
The reciprocal of x is 1x
Suppose the number is 11
Now, its multiplicative inverse is 111
The product of a multiplicative inverse of a number and a number itself is = 11 x 111 = 1.
