4MA0 Higher January 2012 Paper 4 Q7
7 Express 200 as a product of powers of its prime factors.
(3)
| Scheme | Marks |
|---|---|
| Fully correct factor tree or repeated division or 2, 2, 2, 5, 5 or 2 × 2 × 2 × 5 × 5 | M2 |
| \(2^3 \times 5^2\) | A1 |
| (Total 3 marks) |
Notes
M2: M1 for factor tree or repeated division with 2 and 5 as factors
A1: Also accept \(2^3.5^2\)
Apart from Questions 3, 13(b) and 17(f) (where the mark scheme states otherwise), the correct answer, unless clearly obtained by an incorrect method, should be taken to imply a correct method.
