4MA0 Higher January 2012 Paper 4 Q8
8 \[\dfrac{y^3 \times y^n}{y} = y^6\] Find the value of \(n\).
(2)
| Scheme | Marks |
|---|---|
\(y^{3+n-1} = y^6\) oe or \(y^{3+n} = y^7\) oe or \(3 + n - 1 = 6\) oe or \(y^n = \dfrac{y^7}{y^3}\) or \(y^n = \dfrac{y^6}{y^2}\) or \(y^n = y^4\) | M1 |
| 4 | A1 |
| (Total 2 marks) |
Notes
A1: cao
SC if M0, award B1 for an answer of \(y^4\)
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.
