That's correct! $4^2 = 4 \times 4 = 16$.

Would you like any additional details or help with other exponents?

Here are five related questions that expand on this concept:

1. What is $5^2$?
2. How does $4^3$ compare to $4^2$?
3. What is the square root of 16?
4. Can you explain why any number raised to the power of 0 is equal to 1?
5. How would you calculate $4^{1/2}$?

Tip: Squaring a number always results in a positive outcome.
