(a) Write \(6.04 \times 10^5\) as an ordinary number. (1)
(b) Write 0.000 07 in standard form. (1)
(c) Work out \(\quad \dfrac{7.6 \times 10^{10}}{4 \times 10^5 - 2 \times 10^4}\)

| Scheme | Marks |
|---|---|
| 604 000 | B1 |
| (1) |
| Scheme | Marks |
|---|---|
| \(7 \times 10^{-5}\) | B1 |
| (1) |
| Scheme | Marks |
|---|---|
| 380 000 or \(3.8 \times 10^5\) or \(38 \times 10^4\) oe | M1 |
| Working not required, so correct answer scores full marks (unless from obvious incorrect working) Answer: \(2 \times 10^5\) | A1 |
| (2) | |
| (4 marks) |
Notes
A1: Accept \(2.0 \times 10^5\) or \(2.00 \times 10^5\) etc
Accept a dot or a comma for a multiplication sign eg \(2 , 10^5\) / \(2 . 10^5\)
SC B1 for 200 000 or \(20 \times 10^4\) or \(0.2 \times 10^6\) oe or \(2 \times 10^n\) where \(n \neq 5\) when given as a final answer (not for incorrect simplification of the denominator)
