Question

Preciso de ajudaaaa aaaaa √2a² • √6a⁴

Answer 1

$\sqrt{2 {a}^{2} } \times \sqrt{6 {a}^{4} } = \\ \sqrt{2 \times 6 \times {a}^{2} \times {a}^{4} } = \\ \sqrt{12 {a}^{6} } = \\ \sqrt{ {2}^{2} \times 3 } \times \sqrt{ {a}^{6} } = \\ {2}^{ \frac{2}{2} } \times \sqrt{3} \times {a}^{ \frac{6}{2} } = \\ {2}^{1} \times \sqrt{3} \times {a}^{3} = \\ 2 \sqrt{3} {a}^{3}$

Answer 2

$\sqrt{2 {a}^{2} }$
o a sai da raiz perdendo o expoente.
$a \sqrt{2}$

$\sqrt{6} {a}^{4}$
o a sai da raiz perdendo 2 do expoente.
${a}^{2} \sqrt{6}$
$a \sqrt{2} \times {a}^{2} \sqrt{6}$
raiz de 2= 1,4
raiz de 6 = 2,4
${a}^{3} \sqrt{4} \times 3 \\ 2 {a}^{3} \sqrt{3}$
