The mathematical notation '8²' represents which of the following?

8 + 2
8 × 2
8 to the power of 2
The square root of 8

The correct answer is: 8 to the power of 2

The notation '8²' signifies "8 raised to the power of 2," which means multiplying 8 by itself. This is a fundamental concept in mathematics referred to as exponentiation. When you see a number followed by a superscript, it indicates how many times to use that number in multiplication. Therefore, '8²' equals 8 × 8, resulting in 64. The other interpretations don't align with this mathematical notation. Adding 2 to 8, simply performing a multiplication of 8 and 2, or finding the square root of 8 do not reflect what exponentiation entails. Thus, the correct representation of '8²' is indeed 8 to the power of 2.
