Techniques to Simplify Surds with an Example

How do we simplify this long expression so that we can find the value of k? The idea is to simplify it so that we can compare both sides of the equation to get the value of k. Here are some techniques we can use to do this! ⭐️ (1) Use the properties of surds to help you. ⭐️ (2) Think about the factors of the number within the surds that can be square rooted, then split them out using the multiplication property of a surd. ⭐️ (3) Rationalise the fraction to remove a surd from the denominator.
