Answer:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

Step-by-step explanation:

We are talking about the multiplicative inverse of any number. The multiplicative inverse of a number is another number that multiplied by the first, results in the neutral element of the product, that is, the unit. If we have a real number a, then its multiplicative inverse is denoted by a^{-1}, and it is true that:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

It's important to note that the multiplicative inverse exists in rational numbers, in real numbers, and in complex numbers.
