Learning Objective
At the end of the lesson, you will understand and apply the laws of exponents to simplify expressions.
What do you already know about the rules for handling exponents?
What are Exponents?
Exponents represent repeated multiplication of a number by itself. Example: 3^4 means 3 multiplied by itself 4 times.
Product of Powers Law
When multiplying with the same base, add exponents: a^m * a^n = a^(m+n).
Quotient of Powers Law
When dividing with the same base, subtract exponents: a^m / a^n = a^(m-n).
Power of a Power Law
When raising a power to another power, multiply exponents: (a^m)^n = a^(m*n).
Power of a Product Law
Distribute the exponent to each factor inside the parentheses: (ab)^n = a^n * b^n.
Zero and Negative Exponents
a^0 = 1 and a^(-n) = 1/a^n. Negative exponents indicate reciprocals.
Interactive Practice
Solve: Simplify (x^3 * x^4) / x^2 and (2ab^2)^3.
