Answer 1

$a = \sqrt{2 {}^{2} +2 {}^{2} } = \sqrt{2 \times 2 {}^{2} } = \sqrt{2 {}^{3} } = 2 \sqrt{2}$

$b = \sqrt{2 {}^{4} + 2 {}^{4} } = \sqrt{2 \times {2}^{4} } = \sqrt{2 {}^{5} } = {2}^{2} \sqrt{2} = 4 \sqrt{2}$

$a + b = 2 \sqrt{2} \times 4 \sqrt{2} =2 \times 2 \times 4 = 4 \times 4 = 16$

raspuns corect: 16
