(1除以A)+(1除以B)=3,求(3A+2AB+3B)除以(2A-3AB+2B)的值
展开全部
(3A+2AB+3B)/(2A-3AB+2B)
=[(3A+2AB+3B)/(AB)]/[(2A-3AB+2B)/(AB)]
=[3(1/A+1/B)+2]/[2(1/A+1/B)-3]
=(3*3+2)/(2*3-3)
=11/3
=[(3A+2AB+3B)/(AB)]/[(2A-3AB+2B)/(AB)]
=[3(1/A+1/B)+2]/[2(1/A+1/B)-3]
=(3*3+2)/(2*3-3)
=11/3

1/A+1/B=3
(3A+2AB+3B)/(2A-3AB+2B) 上下同除以AB
=(3/A+2+3/B)/(2/A-3+2/B)
=(3*3+2)/(2*3-3)
=11/3
