<h3>What is an integer exponent?</h3>
In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
It is given that:
The expression:

After using the integer exponent property:

= a³b³x¹⁸ Or
=x¹⁸a³b³
Thus, the simplification form of the provided expression is x¹⁸a³b³ option
(d) x¹⁸a³b³ is correct.
