Answer:
[tex]9x^{4}[/tex] for [tex](3x)^2[/tex]· [tex]x^{2}[/tex] and [tex](x^{4})[/tex]·[tex](y^{4})[/tex] for [tex]x^4[/tex]·[tex](y^2)^3[/tex]·[tex]y^{-2}[/tex]
Step-by-step explanation:
[tex](3x)^{2} (x^{2} )[/tex] Multiply in
[tex](9x^{2})(x^{2})[/tex] Multiply together
[tex]9x^{4}[/tex]
[tex](x^{4})(y^{2})^{3} (y^{-2})[/tex]
[tex](x^{4})(y^{6})(\frac{1}{y^{2}})[/tex] Multiply in
[tex](x^{4})(\frac{y^{6}}{y^{2}})[/tex] Multiply together
[tex](x^{4})(y^{4})[/tex]
