Answer 1

hope u understand the method

Answer 2

${x}^{2} = 16 \\ \\ \\ = > {x}^{2} = 2 \times 2 \times 2 \times 2 \\ \\ \\ = > x = \sqrt{2 \times 2 \times 2 \times 2} \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: \: \: \sqrt{ - 2 \times ( - 2) \times ( 2) \times ( 2)} \\ \\ \\ = > x = 2 \times 2 \: \: \: \: \: \: \: or \: \: \: \: - 2 \times 2 \\ \\ \\ = > x = 4 \: \: \: \: \: \: \: or \: \: \: \: \: - 4$
