WebExample 1: Multiplication. Write 5p^2q^3\times3pq^4 5p2q3 × 3pq4 in its simplest form. [2 marks] To simplify this expression, we must recognise that it can be broken up into parts, i.e. we can write. 5p^2q^3\times3pq^4=5\times p^2\times q^3\times3\times p\times q^4 5p2q3 × 3pq4 = 5 × p2 × q3 × 3 × p × q4. WebIntroduction. Surds are numbers left in root form (√) to express its exact value. It has an infinite number of non-recurring decimals. Therefore, surds are irrational numbers. There are certain rules that we follow to simplify an expression involving surds. Rationalising the denominator is one way to simplify these expressions.
