Question: 1 / 400

What is 3 raised to the power of 4?

81

To find 3 raised to the power of 4, you calculate \(3^4\), which means multiplying 3 by itself a total of 4 times. This process can be broken down as follows:

1. First, calculate \(3 \times 3\), which equals 9.

2. Next, take that result (9) and multiply it by 3. So, \(9 \times 3 = 27\).

3. Finally, take the 27 and multiply it by 3 again: \(27 \times 3 = 81\).

Therefore, \(3^4 = 81\). This confirms that the answer is indeed 81, which makes it the correct choice.

To provide some context on the other options: 27 is actually \(3^3\), meaning 3 multiplied by itself three times. The other numbers, 12 and 9, do not represent any powers of 3 in this case and are unrelated to the calculation of \(3^4\).
