5. Find, in standard form, the value of each of the following.
(a) \(\dfrac{7{\cdot}5 \times 10^6}{5000}\) [2]
(b) \((2{\cdot}3 \times 10^3) + (6{\cdot}4 \times 10^4)\) [2]

|---|---|---|
| \(1{\cdot}5 \times 10^3\) | B2 | If B2 not awarded, B1 for sight of 1500 OR B1 for \(1{\cdot}5 \times 10^n\) from a denominator of \(5 \times 10^3\) seen OR B1 for \(a \times 10^3\) with \(1 \leqslant a \lt 10\) from a denominator of \(5 \times 10^3\) seen. |

|---|---|---|
| \(6{\cdot}63 \times 10^4\) | B2 | B1 for \(6{\cdot}6(\ldots) \times 10^4\). B1 for any correct value but not in standard form |
