When we DIVIDE bases, we _____________ exponents. 3. When we RAISE BASES to a POWER, we _________________ the exponents. 4. When we ADD BASES, do we do anything to the exponents? What must we have to ADD bases? Give an example of two terms with powers that CAN be added. 5. Negative exponents _____________________ their base. Negative exponents make nothing negative. For each rule below, write and simplify your own example. Operations with RADICALS To SIMPLIFY radicals with variables, we use __________________________________ to deal with the variable. To ADD/SUBTRACT radicals, we need ___________________________________________ To MULTIPLY/DIVIDE radicals, we need _________________________________________ To RATIONALIZE the denominator, we ___________________________________________ Addition and Subtraction Multiplication Division 1. 50 2 2. 50 3 Complex Numbers Definition: The complex number I is equal to _______________________.
