Simplifying Radicals Binomial Conjugate: Binomial quantity that turns the expression into a difference of squares.

Example 1 Binomials Conjugates

Example 2: Use Binomials Conjugates to Rationalize

The exponent is most often used in the power of monomials. SPECIAL FRACTION EXPONENT: The exponent is most often used in the power of monomials. Examples: Do you notice any other type of mathematical symbols that these special fraction exponents represent?

Radicals: Steps for Simplifying Square Roots Special Fraction Exponents, , are more commonly known as radicals in which the N value represents the root or index of the radical. Index Radical Symbol Radicals: Radicand Note: The square root or ½ exponent is the most common radical and does not need to have the index written. Steps for Simplifying Square Roots Prime Factorization: Factor the Radicand Completely Write the base of all perfect squares (PAIRS) outside of the radical as product Everything else (SINGLES) stays under the radical as a product.

Operations with Rational (Fraction) Exponents The same operations of when to multiply, add, subtract exponents apply with rational (fraction) exponents as did with integer (whole) exponents Hint: Remember how to find common denominators and reduce. 1) 2) 3) 4) 5) 6)
