Verified answer

Explicação passo-a-passo:

[tex]a) \sqrt{49} + \sqrt{16} = 7 + 4 = 11[/tex]

[tex]b) \sqrt[3]{8} - \sqrt[4]{16} = 2 - 2 = 0[/tex]

[tex]c) - 5 \sqrt{9} + 2 \sqrt{169} = - 5.3 + 2.13 = - 15 + 26 = 11[/tex]

[tex]10 {}^{3} \sqrt{2} + 4 {}^{3} \sqrt{2} - \sqrt[3]{2} = 1000 \sqrt{2} + 64 \sqrt{2} - \sqrt[3]{2} = 1.064 \sqrt{2} - \sqrt[3]{2} [/tex]

[tex]e) \sqrt{18} + 2 \sqrt{50} = \sqrt{3 {}^{2} .2} + 2 \sqrt{2.5 {}^{2} } = 3 \sqrt{2} + 50 \sqrt{2} = 52 \sqrt{2} [/tex]
