# Properties of Exponents

Example

Write the following without using a negative exponent and then simplify:

a. (-3)4

b- -34

c. (-3)-4

d. -3-4

Solution

 a. Write (-3)4 as a product. (-3)4 = (-3)(-3)(-3)(-3) Multiply. = 81 Thus, (-3)4 = 81. b. -34 is the opposite of 34. -34 = -(34) Write 34 as a product. = -(3 Â· 3 Â· 3 Â· 3) Multiply. = -81 So, -34 = -81. c. Use the definition (-3)-4 Write (-3)4 as a product. Multiply. Thus, d. -3-4 is the opposite of 3-4. That is, -3-4 = -(3-4 ) Use the definition -(3-4 ) Write 34 as a product. Multiply. Thus,
