Presentation on theme: "Introduction to Irrational Numbers We write “irrational numbers” using a “radical symbol,” often just referred to as a “radical.” √ 3 is an irrational."— Presentation transcript:
How do you simplify variables in the radical? Look at these examples and try to find the pattern… What is the answer to ? As a general rule, divide the exponent by two. The remainder stays in the radical.
4. Simplify Find a perfect square that goes into 49. 5. Simplify
Adding & Subtracting Radicals The rules for adding and subtracting radicals are very similar to the rules for adding and subtracting polynomials. The radical / radicand have to match exactly in order to add or subtract.
