(a) Write these numbers in order, starting with the smallest.\[2.4 \times 10^2 \qquad 1.3 \times 10^3 \qquad 4.9 \times 10^{-1} \qquad 9.5 \times 10^1\] [1]
(b) Work out.
\(5 \times 10^2 + 4 \times 10^3\)
Give your answer in standard form. [2]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(4.9 \times 10^{-1}\), \(9.5 \times 10^1\), \(2.4 \times 10^2\), \(1.3 \times 10^3\), | 1 | Mark the answer line and look for order of indices –1, 1, 2, 3 Condone TE if unambiguous If answer given as ordinary numbers must be correct 0.49, 95, 240, 1300 | |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(4.5 \times 10^3\) | 2 | B1 for 4500 or for 500 and 4000 | For B1 accept poor form e.g. \(45 \times 10^2\) |
