Expands on problems from Square Roots and Radicals 18 with more examples rationalizing the denominator.
  • How do you rationalize the denominator of a fraction when it contains a radical binomial expression?
  • How do you find the conjugate of a radical binomial?
  • What is the conjugate of a radical binomial expression?
  • How do you simplify and rationalize the denominator of 8/((3 * square root of 2) - 2)?
  • Why should you multiply the denominator before the numerator when you are rationalizing a radical binomial denominator?
  • How do you simplify and rationalize the denominator of (3 + square root of 2)/(4 - square root of 5)?
  • How do you simplify and rationalize the denominator of (square root of 7 + square root of 3)/(square root of 7 - square root of 3)?
  • How do you simplify and rationalize the denominator of ((5 * square root of 2) + 3)/(square root of 2)?
More example problems for rationalizing the denominator of a fraction with a radical binomial in the denominator are shown. These problems are rather complicated and can be very difficult for students, so this is a great tutorial to learn some easy methods for simplifying these expressions. This is a must-watch for anyone struggling with rationalizing the denominator.
