Transcript

• 1. RADICALS radicand index The nth root of a number k is a number r which, when raised to the power of n , equals k r
• 2. RADICALS r So, means that r n =k
• 3. Rational exponents We usually express roots this way! Rational exponent
• 4. Rational exponents So, these three ways to express roots are equivalent! Notice that when you are dealing with a radical expression, you can convert it to an expression containing a rational (fractional) power.  This conversion may make the problem easier to solve .
