Question

(-0,4x⁵ y⁶z²)(-1,2xyz³)

Answer 1

Ответ:

0.48x⁶y⁷z⁵

Объяснение:

-0.4+(-1.2)=0.48

x×x⁵=x⁶

y×y⁶=y⁷

z³×z²=z⁵

Answer 2

Объяснение:

$( - 0.4x {}^{5} y {}^{6} z {}^{2} )( - 1.2xyz {}^{3} ) =-0.4x^{6}y^{6}z^{2}\left(-1.2\right)yz^{3} =-0.4x^{6}y^{7}z^{2}\left(-1.2\right)z^{3} =-0.4x^{6}y^{7}z^{5}\left(-1.2\right) =0.48x^{6}y^{7}z^{5}$
