Higher November 2017 Unit 1 Q16
16. You are given that \(p = \sqrt{40}\) and \(q = \sqrt{10}\).
Circle the correct answer in each of the following:
(a) \(p\) is equal to [1]
\(10\sqrt{4}\) \(4\sqrt{10}\) \(10\sqrt{2}\) \(2\sqrt{10}\) 20
(b) \(pq\) is equal to [1]
\(10\sqrt{40}\) \(40\sqrt{10}\) 400 200 20
(c) \(q^5\) is equal to [1]
\(100\sqrt{10}\) \(5\sqrt{10}\) \(\sqrt{50}\) 625 \(10\sqrt{100}\)
