1. (-2x+3y)²
= -2x²+2.-2x.3y+(3y)²
= -4x²+(-12)xy+9y²
2. (4x+2y)3
= 4x³+3.4x².2y+3.4x.2y²+(2y)³
= 64x³+96x²y+48xy²+8y³
3. (-8p-3g)⁴
= -8p⁴-4.-8p³(3g)+6.-8p²(3g)²-4.-8p(3g)³+(3g)⁴
= 4096p⁴-(-6144)p³g+3456p²g²-(-864)pg³+81g⁴
4. (2a+5b)⁵
= 2a⁵+5.2a⁴(5b)+10.2a³ (5b)²+10.2a²(5b)³+5.2a(5b)⁴+(5b)⁵
= 32a⁵+400a⁴b+2000a³b²+5000a2b³+6250ab⁴+3125b5⁵
