This document discusses laws of exponents. It introduces key terms like exponent, base, and power. It then outlines several laws of exponents:
1) The product law states that when multiplying powers with the same base, add the exponents.
2) The quotient law states that when dividing powers with the same base, subtract the exponents.
3) The power law states that when simplifying a power of a power, multiply the exponents.
It also discusses how to simplify expressions using these laws and how to evaluate exponential expressions.

Example: 4-3 not in simplest form 1 simplest form 64 <br />Lesson 1: Laws of Exponents Simplifying an Exponential Expression Exponential expressions are algebraic expressions which contain exponents. An algebraic expression is in simplest form when it is written with only positive exponents. If The expression is a fraction in simplest form, the only common factor of the numerator and denominator is 1. <br />Lesson 1: Laws of Exponents Evaluating an Exponential Expression To evaluate means to substitute the given value/s to the variable/s of the expression and simplifying the expression. <br />
