Number sense
Rationalise the denominator
CCSS HSN.RN.A.2England: GCSE Higher Number
Example
Rationalise: 4/√2 = k√2. What is k?
- 4/√2 × √2/√2 = 4√2/2
- = 2√2
Answer: 2
Builds on: Simplify surds (radicals)
Leads to: Rationalise denominators like a + √b
Rationalise denominators like a + √b
CCSS HSN.RN.B.3England: GCSE Higher Number
Example
Rationalise 1/(4 − √6). What is the denominator after rationalising?
- (4 + √6)(4 − √6) = 16 − 6
- = 10
Answer: 10
Builds on: Rationalise the denominator, Add and subtract surds
