EVALUATING EXPRESSIONS HAVING EXPONENTS • An exponent indicates how many times to multiply the number by itself: 152 253 84 105 • Evaluating an expression containing a number with an exponent means to write the repeated multiplication form and perform the operation. 152 =15 x 15 = 225 253 =25 x 25 x 25 = 15,625 84 = 8 x 8 x 8 x 8 = 4096 105 =10 x 10 x 10 x 10 x 10 = 100,000 How to evaluate expressions having exponents: • Change the number with the exponent into its repeated multiplication form: 122 =12 x 12 • Perform the repeated multiplication operation: 122 =12 x 12 = 144 • If the number with the exponent is in a 2-step problem, evaluate the exponent first and then perform the other operations: 122 + 5 = (12 x 12) + 5 = 144 + 5 = 149 © Copyright NewPath Learning.
