MATH TERMS FOR EXPONENTS
Exponent: shows how many
times a number, the base, is multiplied by itself
Base: the number that is multiplied by itself
Coefficient: a constant number that multiplies a variable
Example: 4x2 --> 4 is the coefficient; x is the base; 2 is the exponent
RULES FOR EXPONENT
PROBLEMS
Bases are the Same Exponents are the Same
Addition Raise
bases to the power, then add Raise
bases to the power, then add
[ex.
42 + 43 = 16 + 64 = 80]
[ex.
52 + 42 = 25 +16 = 41]
Subtraction Raise
bases to the power, then subtract Raise
bases to the power, then subtract
[ex. 42 - 43
= 16 - 64 = -48]
[ex. 52 - 42 = 25 -16
= 9]
Multiplication Keep
the base , then add the exponents
Keep
the exponent, then multiply the bases
[ex.
32× 33 = 3(2 + 3) = 35]
[ex.
32× 52 = (3×5)2 = 152]
Division
Keep the
base , then subtract the exponents
Keep
the exponent , then divide the bases
[ex. 36 ÷
34 = 3(6-4) = 32]
[ex.
62÷ 32 = 22 = 4]
Raising to a Power
Keep the base , then multiply the exponents
Keep the base , then multiply the exponents
[ex. (23)7
= 2(3×7) = 221]
[ex. (23)3 = 29 = 512]
