Unformatted text preview: Lecture 2: Section A.2 Exponents and Radicals Integer Exponents Def. If u1D44E is a real number and u1D45B is a positive integer, then u1D44E u1D45B = where u1D44E is the base and u1D45B is the exponent or power . ex. ( 3) 4 = 3 4 = ( 2) 3 = 2 3 = NOTE: 1) Zero exponent: If u1D44E = 0, then u1D44E = 2) Negative exponents: if u1D44E = 0 and u1D45B is a positive integer, then u1D44E u1D45B = Properties of Exponents Let u1D44E and u1D44F be nonzero real numbers, variables, or algebraic expressions, and let u1D45A and u1D45B be integers. 1. u1D44E u1D45A u1D44E u1D45B = 2. u1D44E u1D45A u1D44E u1D45B = 3. ( u1D44Eu1D44F ) u1D45A = 4. ( u1D44E u1D45A ) u1D45B = 5. uni0028.alt02 u1D44E u1D44F uni0029.alt02 u1D45A = 6. u1D44E 2 = u1D44E 2 = u1D44E 2 NOTE: 1. uni0028.alt02 u1D44E u1D44F uni0029.alt02 u1D45A = 2. u1D44E u1D45A u1D44F u1D45B = ex. Simplify each expression, writing answers without negative exponents....
