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 ... WebMay 11, 2013 · The Corbettmaths video tutorial on Surds.

Web-xy must be a negative real number because x and y are both positive real numbers. On the other hand, ⁺√ (ab) = √ [ (xi)² (yi)²] = (xyi²)² = (xy)² Since ⁺√ (ab) = (xy)² and ⁺√a • ⁺√b = -xy, our problem becomes to prove that: (xy)² ≠ -xy For x, y > 0 Well this is easy! WebMay 12, 2024 · 1 So first remember some key rules: a × a = a a × b = a b (which you can simplify usually) (There are more but we only really need these!) So a good technique to use in this question is called rationalising the denominator. Which basically means take the denominator of the surd and change the middle sign so 3 7 + 5 2 turns into 3 7 − 5 2.
