B$\sqrt{32^{2} } .\sqrt{20^{2} } =$
C$\sqrt[5]{3^{2} } .\sqrt[5]{3^{3} }$
D$2.\sqrt{2}.\sqrt{18}$
E$\sqrt[3]{5^{6} }$
F$\sqrt{3]{8.64}$

Answer 1

a)

√49 . √36 . 25

= 7 . √36 . √25

= 7 . 6 . 5

= 210

c)

⁵√3² . ⁵√3³

= ⁵√(3² . 3³)

= ⁵√3⁵

= 3

d)

2 . √2 . √18

= 2 . √(2 . 18)

= 2 . √36

= 2 . 6

= 12

e)

∛5⁶

= ∛(5³ . 5³)

= 5 . 5

= 25
