分析:(1)根據(jù)同底數(shù)冪相乘,底數(shù)不變,冪相加即可得出答案;
(2)根據(jù)單項(xiàng)式乘以單項(xiàng)式法則即可得出答案;
(3)根據(jù)同底數(shù)冪相乘,底數(shù)不變,冪相加即可得出答案;
(4)根據(jù)多項(xiàng)式乘以多項(xiàng)式即可得出答案;
(5)根據(jù)多項(xiàng)式除以單項(xiàng)式的法則即可得出答案;
(6)根據(jù)多項(xiàng)式乘以多項(xiàng)式法則即可得出答案;
解答:解:(1)a3•a2=a3+2=a5;
(2)(-3x2y)2=(-3)2x4y2=9x4y2;
(3) 2m2n•(-5m4)=-10m2+4n=-10m6n;
(4)(x+1)(x-6)=x2-6x+x-6=x2-5x-6;
(5)(6a2-10ab+2a)÷2a=6a2÷2a-10ab÷2a+2a÷2a=3a-5b+1;
(6)(x+2y)2=x2+2x•2y+4y2=x2+4xy+4y2.
點(diǎn)評(píng):本題主要考查整式混合運(yùn)算中的公式和法則,屬于基礎(chǔ)題,熟記公式和法則是解題的關(guān)鍵.
