Mastering the Power of a Number

In mathematics, understanding the power of a number is crucial, as it is widely utilized across various fields such as finance, engineering, and computer science. The power of a number, also known as exponentiation, involves raising a base number to the power of an exponent. This operation is elegantly represented using the formula: P = baseexponent. In this formula, P is the product (the resultant value), base is the number being multiplied, and exponent is the number of times the base is multiplied by itself.

Real-Life Examples

Understanding the power of a number can be elucidated with practical examples:

Example 1: Calculating Compound Interest

In finance, compound interest can be calculated using powers. If you invest $1,000 (base) at an annual interest rate of 5% for 3 years (exponent), the compounded value is calculated as: 1000 * (1 + 0.05)3 = 1000 * 1.157625 = $1157.63
The formula used here is: base * (1 + rate)exponent.

Example 2: Growth of a Bacterial Culture

Suppose a bacterial culture quadruples every hour. Starting with 1 bacterium (base), the number of bacteria after 4 hours (exponent) is: 1 * 44 = 1 * 256 = 256 bacteria.
