Question

Fatore as equações:

√a³+√a² =
√a^9+√a^7 =

Answer 1

$\sqrt{ a^{3} }+ \sqrt{ a^{2} }=$

$\sqrt{ a^{2}.a }+ \sqrt{ a^{2} }=$

$a \sqrt{a} +a=a( \sqrt{a}+1)$
_______________________________________________
$\sqrt{ a^{9} }+ \sqrt{ a^{7} } =$

$\sqrt{ a^{8}.a }+ \sqrt{ a^{6}.a } =$

$a^{4} \sqrt{a}+ a^{3} \sqrt{a}=$

$a^{3} \sqrt{a}(a+1)$
