Answer 1

a)

$4\sqrt{2} + 5 \sqrt{2}$

$9 \sqrt{2}$

b)

$2 \sqrt[3]{2} + 3 \sqrt[3]{2} - \sqrt[3]{2}$

$4 \sqrt[3]{2}$

c)

$\sqrt{200} - 3 \times 6 \sqrt{2} + \sqrt{12}$

$\sqrt{200 } - 18 \sqrt{2} + \sqrt{12}$

$\sqrt{2} ( \sqrt{100} - 18 \sqrt{6})$

$\sqrt{2}( - 10 - 16 + \sqrt{6} )$

$\sqrt{2} ( - 8 + \sqrt{6} )$

d)

$8 \sqrt{3} + 9 \sqrt{3}$

$17 \sqrt{3}$
