tolong di jawab yyyy tanpa pakai tanda titikkkk.......

1. (3x+2y)² =
(3x+2y)(3x+2y) = 9x²+6xy+6xy+4y²=9x²+12xy+4y²
2. (2x+ 3y)⁴ =
(2x+ 3y)(2x+ 3y)(2x+ 3y)(2x+ 3y)=
(4x²+6xy+6xy+9y²)(4x²+6xy+6xy+9y²)=
(4x²+12xy+9y²)(4x²+12xy+9y²)=
16x⁴+48x²y²+36x²y²+48x²y²+144x²y²+108xy³+36x²y²+108xy³+81y⁴=
16x⁴+81y⁴+48x²y²+36x²y²+48x²y²+144x²y²+36x²y²+108xy³+108xy³=
16x⁴+81y⁴+312x²y²+216xy³
