Key Concepts

Even Exponents and Negative Bases

When a negative number is raised to an even exponent, the result is positive. This is because the multiplication of an even number of negative factors cancels out the negative sign in pairs, leading to a positive product. Evaluating (-2)^8 involves multiplying -2 by itself eight times, resulting in a positive value.

Exponentiation

Exponentiation refers to the mathematical operation of multiplying a number (the base) by itself a specified number of times (the exponent). In this context, raising a number to a power means carrying out repeated multiplication, where the exponent tells how many times to multiply the base by itself.
