Understanding Exponents
Exponents are a shorthand way of expressing repeated multiplication. The general form of an exponent is a^b, where 'a' is the base and 'b' is the exponent. In the case of 2 power of 5, the base is 2 and the exponent is 5. This means we multiply 2 by itself five times:
2^5 = 2 * 2 * 2 * 2 * 2
Calculating this step-by-step:
