The expression shown in the image is $5^2$.

To evaluate $5^2$:

$5^2 = 5 \times 5 = 25$

So, the result is 25.

Would you like further details or explanations on this?

Here are five follow-up questions to expand your knowledge:

1. What is the difference between evaluating $5^2$ and $5^3$?
2. How would you solve $10^2$?
3. Can you explain why any number raised to the power of 1 is the number itself?
4. What does it mean when a number is raised to the power of 0?
5. What is the result of $(-5)^2$?

Tip: When you square a number, you are multiplying the number by itself. This applies to both positive and negative numbers, but be careful with parentheses when squaring negative numbers.
