ZERO POWER EQUALS 1!!! 90 = 1

Equals 1 divided by that power with its opposite exponent. NEGATIVE EXPONENTS Equals 1 divided by that power with its opposite exponent. 5-3 =

(-5)-3

Keep the base and add the exponents. MULTIPLY POWERS Must have the same base!!! Keep the base and add the exponents. 35 • 38 =

49 • 44 =

4-7 • 42 =

2x2 • 4x4 =

Keep the base and subtract the exponents. DIVIDE POWERS Must have the same base!!! Keep the base and subtract the exponents. 69 64

6x4 6x9

POWER to Power Multiply exponents! (32)3

(-32)-3

(7 – 5)9 (8 – 6)4

(-5 + 9)-3• (8 - 4)9

(-5y + 9y)2 + (22)2

[-5 + 2(3)]2 - (2x – 4x)3

(-5y ● 9y) + (9 - 4)2 + (-8y)2

(-5 + 9)-2 ● (7 - 4)2

(-5 + 9)-3• (3x2 ÷ 3x)2
