The expression visible in the image is $(-3)^4$.

Let's solve it step by step:

1. When raising a negative number to an even power, the result is positive.
2. $(-3)^4 = (-3) \times (-3) \times (-3) \times (-3)$
3. The result of this is: $(-3) \times (-3) = 9$ $9 \times (-3) = -27$ $-27 \times (-3) = 81$

So, $(-3)^4 = 81$.

Let me know if you'd like further details or have any other questions.

Here are 5 questions based on this:

1. What is the result of $(-2)^5$?
2. How do powers of negative numbers change with odd vs even exponents?
3. Can you explain why $(-1)^n$ equals 1 or -1 depending on $n$?
4. What happens if the negative sign is outside the parentheses in $-3^4$?
5. How do powers of fractions work with negative bases?

Tip: When dealing with negative numbers raised to a power, always check if the exponent is even or odd—this determines whether the result will be positive or negative!
