 calcule ³√8-⁴√16 =

-5√9+2√169 =

10³√2+4³√2-³√2 =

√18+2√50 =

Answer 1

$\sqrt[4]{2 ^{4} } = 2$
$\sqrt[3]{2 ^{3} } = 2$
2 - 2 = 0

$-5 \sqrt{3 ^{2} } + 2 \sqrt{13 ^{2} } = -5.3 + 2.13 = -15 + 26 = 11$

$13 \sqrt[3]{2}$

$\sqrt{18} = \sqrt{2.3 ^{2} } = 3 \sqrt{2}$
$2 \sqrt{50} = 2 \sqrt{2.5 ^{2} } = 2 . 5 \sqrt{2} = 10 \sqrt{2}$
$3 \sqrt{2} + 10 \sqrt{2} = 13 \sqrt{2}$
