1
(a) Simplify \(g^6 \times g^4\) (1)
(b) Simplify \(k^{10} \div k^3\) (1)
(c) Simplify \((3cd^4)^2\) (2)
(d) Solve the inequality \(4x + 7 \gt 2\) (2)
| Scheme | Marks |
|---|---|
| \(g^{10}\) | B1 |
| (1) |
| Scheme | Marks |
|---|---|
| \(k^7\) | B1 |
| (1) |
| Scheme | Marks |
|---|---|
| \(9c^2d^8\) | B2 |
| (2) |
Notes
B2: B1 for 2 out of 3 terms correct in a product
| Scheme | Marks |
|---|---|
| \(4x \gt 2 - 7\) oe | M1 |
| Correct answer scores full marks (unless from obvious incorrect working) Answer: \(x \gt -1.25\) | A1 |
| (2) | |
| (6 marks) |
Notes
M1: accept as an equation or with wrong inequality sign.
A1: oe allow \((-1.25, (+)\infty)\)
Note: award M1A0 for an answer on the answer line of \(-1.25\) with no sign or the incorrect sign eg \(x = -1.25\), \(x \lt -1.25\)
