The answer to the question is the second and third equations

Step-by-step explanation:

[tex]x^m\time x^n=x^{m+n}[/tex] Formula used

1) [tex]-5x^3(3x^3+2)\neq -15x^9-10x^3[/tex]

[tex]-15x^6-10x^3=-15x^9-10x^3[/tex]   (Incorrect)

2)[tex]-3y^5(2y^3+3)=-6y^8-9y^5[/tex]

[tex]-6y^8-9y^5=-6y^8-9y^5[/tex]   (Correct)

3)[tex]-2c^6(5c^3+6)=-10c^9-12c^6[/tex]

[tex]-10c^9-12c^6=-10c^9-12c^6[/tex]    (Correct)

4)[tex]-4b^4(5b^2+6)=-20b^8-24b^3[/tex]

[tex]-20b^6-24b^4\neq -20b^8-24b^3[/tex]   (Incorrect)
