Answer 1

12)
$\sqrt[15]{x^4y^2}. \sqrt[15]{xy^3}=$

$\sqrt[15]{x^4y^2.xy^3}=$

$\sqrt[15]{x^4x^1.y^2y^3}=$

$\sqrt[15]{x^5y^5}=$

$\sqrt[15]{(xy)^5}=$

$\sqrt[3]{xy}$

13)
$\frac{ \sqrt[14]{a^3} }{ \sqrt[14]{a^2} }. \sqrt[14]{a}=$

$\sqrt[14]{ \frac{a^3}{a^2} }.\sqrt[14]{a}=$

$\sqrt[14]{a^3^-^2}.\sqrt[14]{a}=$

$\sqrt[14]{a^1}.\sqrt[14]{a}=$

$\sqrt[14]{a^1.a^1}=$

$\sqrt[14]{a^1^+^1}=$

$\sqrt[14]{a^2}=$

$\sqrt[7]{a}$
