Answer 1

We want to mutiply

(1).

`2x^3y^3*3y^4=6x^3y^7`

(2).

`3vu^2*3vu^2=9v^2u^4`

(3).

`yx^3* x^3*3yx^4=3x^(10)y^2`

(4).

`2x^2y^2*4x^3y^4=8x^5y^6`

(5).

`-8x^2(7x-2)=-56x^3+16x^2`

(6).

`5x(4x+6)=20x^2+30x`

(7).

`2k(k-1)=2k^2-2k`

(8).

`-4m^4(5m-8n)=-20m^5+32m^4n`

(9).

`8a^2(a^2-5a+5)=8a^4-40a^3+40a^2`

(10).

`5p(7p^2+9p-7)=35p^3+45p^2-35p`
