Answer 1

=256 nhé

Answer 2

x²yz³=4³

xy²=4⁹

=>(x²yz³).(xy²)=4³.4⁹

=>x³y³z³=4¹²

=>(xyz)³=4¹²

=>xyz= \(\sqrt[3]{4^{12}}\)

^=>xyz=256

Answer 3

Ta có: x²yx³=4³

xy²=4⁹

\(\Rightarrow\)(x²yx³).(xy²)=4³.4⁹

\(\Rightarrow\)x³y³z³=4¹²

\(\Rightarrow\left(xyz\right)^3=4^{12}\)

\(\Rightarrow xyz=\sqrt[3]{4^{12}}\)

\(\Rightarrow\) xyz= 256
