1. Evaluating Expression When Exponents are Integers

2. 2 5 =2 · 2 · 2 · 2 · 2=32 2 4 =2 · 2 · 2 · 2=16 2 3 =2 · 2 · 2=8 2 2 =2 · 2=4 2 1 =2=2 2 0 =1=1 == ÷2 2 -1 2 -2 1/21/2 1 / 2 · 2 1/21/2 1/41/4 ÷2 = = 1221222 121121

3. Write the expression using positive exponents. 4 -5 = 145145 8 -3 = 183183 10 -6 = 1 10 6 2 -18 = 1 2 18 12 8 = 1 12 -8 7272 = 1 7 -2

4. If the exponent is negative, then it equals a fraction with one over the same base with the positive version of the exponent.
