Exponent Rule #1
Add the Exponents
Copyright © 2013 Lynda Aguirre 4
To add or subtract fractionsyou need the same
denominators(bottoms)

Exponent Rule #2
Multiply the Exponents
Copyright © 2013 Lynda Aguirre 7
To multiply fractionsMultiply straight across
(tops, then bottoms)

RadicalForm
Read the instructions to see whether the answer should be in
Rational Form or Radical Form .

Exponent Rule #3
Subtract the Exponents
Copyright © 2013 Lynda Aguirre 9
To subtract fractionsYou must have common
denominators (The same number on the bottom)
RationalForm
RadicalForm
Read the instructions to see whether the answer should be in
Rational Form or Radical Form .
Note: Always check to see if you can reduce the fractions and simplify radicals

PARKING TICKET: This term is in the wrong parking place. Move
it and remove the ticket (the negative sign)
1) Write as a fraction
RationalForm
RadicalForm
3) Remove the negative power
Simplify the radical: splitting property
