Introduction to Exponents

r r

In mathematics, an exponent (also known as a power) is a notation that indicates how many times a number (the base) is multiplied by itself. For instance, in the expression x^2, the exponent of 2 signifies that x is multiplied by itself twice: x * x. Understanding this basic principle is essential to tackle more complex operations involving exponents.

Multiplying Exponents with the Same Base

r r

When you want to multiply two exponents with the same base, you can add the exponents together. This is based on the exponent rules, which state that a^m * a^n a^(m n). Applying this rule to x^2 * x^2, we get:

r r

1. Identify the base and the exponents. In this case, the base is x, and both exponents are 2.

2. Add the exponents: 2 2 4.

3. Retain the base and apply the new exponent: x^2 * x^2 x^4.

x^2 * x^2 2^2 * 2^2 2^(2 2) 2^4 16.

Dividing Exponents with the Same Base

r r

When dividing, you subtract the exponents: a^m / a^n a^(m-n). For example, x^5 / x^3 x^(5-3) x^2.

Raising a Power to Another Power

r r

When raising a power to another power, you multiply the exponents: (a^m)^n a^(m*n). For instance, ((2^3)^2) 2^(3*2) 2^6 64.
