Exponents (Day 2) Name:_____ Pre-Calculus Write the expression using a radical sign and no negative exponents. 1. 2. 3. Write the expression using positive rational exponents. Any expression that has negative exponents is not considered to be in simplest form. We will use the definition of a negative exponent and other properties of exponents to write the expression with only positive exponents. For example, if after simplifying an expression we end up with the expression, we will take one more step and write. You use negative exponents as a way to combine expressions with the same base, whether the different factors are in the numerator or denominator. It's a way to change division problems into multiplication problems. Example: Instead of writing A reciprocal of a number is the multiplicative inverse of the number.In this expression, we can use the distributive property to get rid of the first two sets of parentheses. Now we can get rid of the parentheses in the term with the exponents by using the exponent rules we learned earlier. When a term with an exponent is raised to a power, we multiply the exponents, so (x 2) 2 becomes x 4.

For example, to indicate the square of − 5, we write. ( − 5)2 = ( − 5)( − 5) = 25 Exponent applies to ( − 5). 🔗. If the negative number is not enclosed in parentheses, then the exponent applies only to the positive number, and the negative sign tells us that the power is negative. Once we take the reciprical the exponent is now positive. Also, it is important to note a negative exponent does not mean the expression is negative, only that we need the reciprocal of the base. Following are the rules of negative exponents. RulesofNegativeExponets: a−m= 1 m 1 a−m. = am.
