b) ⁴√2•⁴√8 =
c) √2•(√7+2) = ​

Answer 1

a) √5•√2 = √10

b) ⁴√2•⁴√8 = ⁴√16 = 2

c) √2•(√7+2) = ​√14+2√2

Answer 2

Oie, Td Bom?!

a)

$\sqrt{5} \sqrt{2}$

$\sqrt{5 \times 2}$

$\sqrt{10}$

b)

$\sqrt[4]{2} \sqrt[4]{8}$

$\sqrt[4]{2 \times 8}$

$\sqrt[4]{16}$

$\sqrt[4]{2 {}^{4} }$

$2$

c)

$\sqrt{2} \times ( \sqrt{7} + 2)$

$\sqrt{2} \sqrt{7} + 2 \sqrt{2}$

$\sqrt{1 4} + 2 \sqrt{2}$
