Answer 1

$a) \\ \sqrt{2 \times x } = 6 \\ 2 \times x = {6}^{2} \\ x = \frac{36}{2} \\ x = 18 \\ \\ b) \\ \sqrt[3]{x + 1} = 2 \\ x + 1 = {2}^{3} \\ x = 8 - 1 \\ x = 7 \\ \\ c) \\ \ \sqrt[4]{5 \times x} = 1 \\ 5 \times x = {1}^{4} \\ x = \frac{1}{5} \\ \\ d) \\ \sqrt{x + 2} = 5 \\ x + 2 = {5}^{2} \\ x = 25 - 2 \\ x = 23$
