LEARNING OBJECTIVE: Develop skills in manipulating and simplifying surds when we have brackets involved

SUCCESS CRITERIA: You will be able to expand a bracket containing at least one surd and then simplify the expression to its simplest form

STARTER

Find the value of a that makes each of these surd statements true

√5 x √a = 10	√6 x √ a =12
√10 x 2√a = 20	2√6 x 3√a = 72
2√a x √a = 6	3√a x 3√a = 54
