|---|---|---|
| (\(\sqrt{97}\) =) \(\sqrt{100}\) or 10 or (\(2.014^3\) =) \(2^3\) or 8 or (0.49 =) 0.5 or \(\dfrac{1}{2}\) | M1 | |
| (\(\sqrt{97}\) =) \(\sqrt{100}\) or 10 and (\(2.014^3\) =) \(2^3\) or 8 and (0.49 =) 0.5 or \(\dfrac{1}{2}\) | M1 | \(\dfrac{10 + 8}{0.5}\) or \(\dfrac{18}{0.5}\) scores M2 |
