Sagot :

Sorry, I'm just using my phone right now. But I can answer that. When it says ³ , you should multiply it three times by itself. So in (x+5)³ , multiply x+5 three times by itself (x+5)(x+5)(x+5) = (x²+10x+25)(x+5) = x³+15x²+75x+125 <--- answer In (x+2y)³ , you do the same (x+2y)(x+2y)(x+2y) = (x²+4xy+4y²)(x+2y) = x³+6x²y+12xy²+8y³ I hope it can help
