How do you simplify a surd
Web2. In general, to simplify a surd, you want to "rationalize the denominator". In this case, that would involve multiplying by 42 to get 3 588 42, factoring out the 196 from the 588 to get 42 3 42, and reducing the fraction to obtain 3. However, one property of square roots is that they can be divided. So, you can simply divide 42 in the ... WebFirst simplify 2√12: 2√12 = 2 × 2√3 = 4√3 Now both terms have √3, we can add them: 4√3 + 9√3 = (4+9)√3 = 13√3 Surds Note: a root we can't simplify further is called a Surd. So √3 is a surd. But √4 = 2 is not a surd. Question 1 Question 2 Question 3 Question 4 Question 5 Question 6 Question 7 Question 8 Question 9 Question 10
