Answer:
Third option: [tex]-10x^7y^2[/tex]
Step-by-step explanation:
[tex]12x^4\left(-\frac{5}{6}x^3y^2\right)[/tex]
Remove brackets:
[tex]12x^4\times-\frac{5}{6}x^3y^2[/tex]
Multiply the [tex]x^2[/tex]:
[tex]12\times-\frac{5}{6}x^{4+3}\times y^2[/tex]
[tex]12\times - \frac{5}{6}x^7y^2[/tex]
Multiply:
[tex]-\frac{5\times \:12x^7y^2}{6}[/tex]
[tex]-\frac{60x^7y^2}{6}[/tex]
Divide:
[tex]-10x^7y^2[/tex]
