Vă rog urgent! Ex 5! Vă rog, am nevoie! ​

[tex]a = \sqrt{2 {}^{2} +2 {}^{2} } = \sqrt{2 \times 2 {}^{2} } = \sqrt{2 {}^{3} } = 2 \sqrt{2} [/tex]

[tex]b = \sqrt{2 {}^{4} + 2 {}^{4} } = \sqrt{2 \times {2}^{4} } = \sqrt{2 {}^{5} } = {2}^{2} \sqrt{2} = 4 \sqrt{2} [/tex]

[tex]a + b = 2 \sqrt{2} \times 4 \sqrt{2} =2 \times 2 \times 4 = 4 \times 4 = 16[/tex]

raspuns corect: 16
