(a) Solve \(\;5m + 7 = 24\) (2)
(b) Make \(t\) the subject of \(\;k = \dfrac{t - e}{2}\) (2)
(c) Simplify \(\;p^8 \div p^3\) (1)
(d) Simplify \(\;n^0\) (1)
(e) Simplify \(\;(3x^2y^5)^3\) (2)
| Scheme | Marks |
|---|---|
| \(5m = 24 - 7\) or \(m + \dfrac{7}{5} = \dfrac{24}{5}\) | M1 |
| 3.4 oe | A1 |
| (2) |
Notes
A1: for 3.4 oe e.g. \(\dfrac{17}{5}\)
| Scheme | Marks |
|---|---|
| \(2k = t - e\) | M1 |
| \(t = 2k + e\) | A1 |
| (2) |
Notes
A1: NB: \(2k + e\) only on answer line scores M1 unless \(t = 2k + e\) in working and then M1A1
