| Answer | Mark | Comments |
|---|---|---|
| \(10^5\) or 25 000 | M1 | oe correct value not in standard form eg \(25 \times 10^3\) |
| \(2.5 \times 10^4\) | A1 |
Additional guidance
| Condone \(2.5 \cdot 10^4\) | M1A1 |
| Condone different spacing or commas eg 2 5000 or 250,00 | M1A0 |
| Answer | Mark | Comments |
|---|---|---|
| \(c = 3\) and \(d = -2\) | B2 | B1 \(c = 3\) or \(d = -2\) or \(c = 10^3\) and/or \(d = 10^{-2}\) |
Additional guidance
One or both of the values may be embedded for B1 only
