Answer 1

a)17
b)5
c)9
d)21
e)30
f)18

Answer 2

$\sqrt{17} X\sqrt{17}$

$\sqrt{289}$

17

$\sqrt[3]{5} X \sqrt[3]{25}$

$\sqrt[3]{5} X \sqrt[3]{5 ^{2} }$

$\sqrt[3]{5} X 5 \frac{2}{3}$

$5$

C) $\sqrt{2} X \sqrt{40.5}$

$\sqrt{2} X 6.36....$

$6.36.... \sqrt{2}$

D) $\sqrt{7} X 3 \sqrt{7}$

$3 \sqrt{7 X 7 }$

$3 \sqrt{49}$

$3 X 7 = 21$


E) $2X \sqrt{5} X 3 X \sqrt{5}$


$2X3 \sqrt{5X5}$

$2X3 \sqrt{25}$

2X3X5=30


F) $\sqrt{3} X \sqrt{6} X \sqrt{6} X \sqrt{3}$

$\sqrt{324} = 18$

18 X 18 = 324
