有數學唔識做？？
發問:
1.(-45y6次方)÷(5y7次方) 2.mn5分之m4次方n6次方 3.3p2次方q分之-12p次方4a次方5 4.(xy3)2次方 5.(6p2次方q3)2次方 要有過程 ,要有三個=
最佳解答:
1 (-45y6次方)÷(5y7次方) = (-45/5)y(6-7) = (-9)y(-1) = -9/y 2 mn5/(m4n6) =m(1-4)n(5-6) =m(-3)n(-1) =1/(m3n) 3 題目太混淆，太亂，請明確表示次方 4 (xy3)2 =x(1*2)y(2*3) =x2y6 5 [(6p2)(q3)]2 =(6*6)p(2*3)q(3*2) =36p6q6
1.(-45y6次方)÷(5y7次方) = (-45/5)y(6-7) = (-9)y(-1) = -9/y 2.mn5/(m4n6) =m(1-4)n(5-6) =m(-3)n(-1) =1/(m3n) 3.3p2次方q分之-12p次方4a次方5 唔明你想點 4.xy3)2 =x(1*2)y(2*3) =x2y6 5.[(6p2)(q3)]2 =(6*6)p(2*3)q(3*2) =36p6q6
