The expression to simplify is:

$(x^2)(x^5)$

To simplify this, use the product of powers property, which states that when multiplying two exponents with the same base, you add the exponents. In this case, the base is $x$, so we add the exponents $2$ and $5$:

$x^2 \cdot x^5 = x^{2+5} = x^7$

Thus, the simplified expression is:

$x^7$

Here are 5 related questions to expand your understanding:

1. How do you simplify $(x^3)(x^4)$?
2. What happens if the exponents are negative, like $(x^{-2})(x^5)$?
3. How do you simplify expressions like $(x^2)(y^5)$ where the bases are different?
4. What is the rule for dividing exponents with the same base, like $\frac{x^5}{x^2}$?
5. How do you handle powers of powers, like $(x^3)^2$?

Tip: Always remember that the base of the powers must be the same to apply the product or quotient of powers rules.
