Answer 1

1-

a) $\sqrt{49} + \sqrt{16} = 7 + 4 = 11$

b) $\sqrt[3]{8} + \sqrt[4]{16} = 2 + 2 = 4$

c) $-5\sqrt{9} + 2\sqrt{169} = -5(3) + 2(13)= 11$

d) $10\sqrt{2} + 4\sqrt{2} - \sqrt{2} = 13\sqrt{2}$

2-

a) $\sqrt{25} + \sqrt[3]{27} + \sqrt[4]{81} = 5 + 3 + 3 = 11$

3-

a) $3\sqrt{5} + \sqrt{5} - 6\sqrt{5} = -2\sqrt{5}$

b) $\sqrt{50} + \sqrt{18} - \sqrt{8} = 5\sqrt{2} + 3\sqrt{2} - 2\sqrt{2} = 6\sqrt{2}$

c) $\sqrt{12} + \sqrt{75} + \sqrt{108} = 2\sqrt{3} + 5\sqrt{3} + 6\sqrt{3} = 13\sqrt{3}$
