Binomial products and surds
WebIn this tutorial we will look at surds of the form n√a a n where a a is any positive number, for example, √7 7 or 3√5 5 3. It is very common for n n to be 2. 2. so we usually do not write 2√a a 2. Instead we write the surd as just √a a. It is sometimes useful to know the approximate value of a surd without having to use a calculator. WebMay 23, 2024 · Class 9: Surds – Lecture Notes. In a very simple way, A surd is a square root which cannot be reduced to a whole number. For example, is not a surd, as the answer is a whole number. But is not a whole number. You could use a calculator to find that but instead of this we often leave our answers in the square root form, as a surd.
