Use fractions in exact calculations without a calculator.
Use multiples of \(π\) in exact calculations without a calculator.
Use surds in exact calculations without a calculator.
#3.03b
Simplify expressions with surds, including rationalising denominators.
e.g. \(\sqrt{12} = 2\sqrt{3}\)
\(\dfrac{1}{\sqrt{3}} = \dfrac{\sqrt{3}}{3}\)
\(\dfrac{1}{\sqrt{3}+1} = \dfrac{\sqrt{3}-1}{2}\)
