Question

Decomponha os radicais​

Answer 1

a)

$\sqrt{48} = \sqrt{16 \times 3} = \sqrt{16} \times \sqrt{3} = 4 \sqrt{3}$

b)

$\sqrt{40} = \sqrt{4 \times 10} = \sqrt{4} \times \sqrt{10} = 2 \sqrt{10}$

c)

$\sqrt[3]{72} = \sqrt[3]{8 \times 9} = \sqrt[3]{8} \times \sqrt[3]{9} = 2 \sqrt[3]{9}$

d)

$\sqrt{243} = \sqrt{81 \times 3} = \sqrt{81} \times \sqrt{3} = 9 \sqrt{3}$
