x^5*x^3 simplify the expression

To simplify the expression x^5 * x^3, you can use the rule of exponents which states that when you multiply two numbers with the same base, you can add their exponents.

In this case, both terms have the base x, so we can add their exponents.

x^5 * x^3 = x^(5+3) = x^8

Therefore, the simplified expression is x^8.
