8 Use your calculator to work out
\[\frac{\sqrt[3]{1.57^4 + \tan 60^\circ}}{7.2^{\frac{1}{2}}}\]Give your answer correct to 3 significant figures. (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| 0.739 | M1 | for partial evaluation, eg 6.07(5732...) or \(\sqrt{7.2}\ (= 2.68(328...))\) or 7.80(778…) or \(\sqrt[3]{7.80(7782818...)}\ (= 1.98(3851871\ldots))\) |
| A1 | for an answer in the range 0.739 to 0.747 |
Additional guidance
