[(-3x的4次方×y²)²]²÷[(-2xy)²]等于多少?还有几道题:(1)(-6分之1×a·b的4次方)³÷(-6分之1×a·b的4次方)²×b的5次方(2)(6·a的5次方·b的6次方·c的4次方)÷(-3
[(-3x的4次方×y²)²]²÷[(-2xy)²]等于多少?
还有几道题:(1)(-6分之1×a·b的4次方)³÷(-6分之1×a·b的4次方)²×b的5次方
(2)(6·a的5次方·b的6次方·c的4次方)÷(-3·a²·b³c)÷(2·a³·b³·c²)
以上三道题都是有关于单项式除以单项式的题目,请大师们帮我解答解答,
[(-3x的4次方×y²)²]²÷[(-2xy)²]等于多少?还有几道题:(1)(-6分之1×a·b的4次方)³÷(-6分之1×a·b的4次方)²×b的5次方(2)(6·a的5次方·b的6次方·c的4次方)÷(-3
[(-3x的4次方×y²)²]²÷[(-2xy)²]
=(-3x的4次方×y²)⁴÷4x²y²
=81x^16y^8÷4x²y²
=81/4x^14y^6
(-6分之1×a·b的4次方)³÷(-6分之1×a·b的4次方)²×b的5次方
=﹣1/216a^3b^12÷1/36a^2b^8*b^5
=﹣1/6ab^4*b^5
=﹣1/6ab^9
(6·a的5次方·b的6次方·c的4次方)÷(-3·a²·b³c)÷(2·a³·b³·c²)
=6·a的5次方·b的6次方·c的4次方÷[(-3·a²·b³c)*(2·a³·b³·c²)]
=6·a的5次方·b的6次方·c的4次方÷(﹣6a^5b^6c^3)
=﹣c
