Identifying Surds: Test Your Knowledge

This video tutorial provides practice questions and answers to help viewers identify surds. It covers determining whether numbers are surds, identifying surds in expressions and equations, classifying numbers as surds or non-surds, and recognizing surds in the context of right-angled triangles. The tutorial encourages viewers to pause and solve problems independently before reviewing the solutions.

For each of the following equations, identify the surds.

In a right-angled triangle, if the length of one of the sides is sqrt 13 and another side is sqrt 12.25, identify which one is a surd.
