Question

упростите выржение $sqrt[4]{8x ^{3} } y ^{5} * sqrt[4]{2xy ^{7} }$

Answer 1

$sqrt[4]{8x^{3}y^{5}} * sqrt[4]{2xy^{7}}= sqrt[4]{16x^{4}y^{12}}=2xy^{3}$

Answer 2

$sqrt[4]{8x^3y^5}*sqrt[4]{2xy^7}=sqrt[4]{8x^3y^5*2xy^7}=sqrt[4]{16x^4y^{12}}=\sqrt[4]{16}*sqrt[4]{x^4}*sqrt[4]{y^{12}}=2*x*y^3=2xy^3$
