Solution:
Given that,
We have to find the multiplicative inverse of [tex]9^3[/tex]
By multiplicative inverse,
The product of a number and its multiplicative inverse is 1
Given number is: [tex]9^3[/tex]
Let "x" be the required multiplicative inverse
Therefore,
[tex]9^3 \times \text{ multiplicative inverse of } 9^3 = 1[/tex]
[tex]9^3 \times x = 1\\\\x = \frac{1}{9^3}[/tex]
Thus the multiplicative inverse of [tex]9^3[/tex] is [tex]\frac{1}{9^3}[/tex]
