8 to the second power, also known as 8 squared, is calculated by multiplying 8 by itself. So, you would perform the following calculation:
8 × 8 = 64
Therefore, 8 to the second power equals 64. This concept is part of exponentiation, where the base (in this case, 8) is raised to an exponent (the power of 2). Squaring a number is a common operation in mathematics and is often used in various applications, such as area calculations and geometry.
