2k/(3k-1)=4k/(3k+2)求k2k/(3k-1)=4k/(3k+2)求k2k/(3k-1)=4k/(3k+2)求k解2k/(3k-1)=4k/(3k+2)∴4k(3k-1)=2k(3k+2
2k/(3k-1)=4k/(3k+2)求k
2k/(3k-1)=4k/(3k+2)求k
2k/(3k-1)=4k/(3k+2)求k
解
2k/(3k-1)=4k/(3k+2)
∴4k(3k-1)=2k(3k+2)
即12k^2-4k=6k^2+4k
∴6k^2-8k=0
∴2k(3k-4)=0
∴k=0,k=4/3
经检验k=0,k=4/3都是方程的解
2k/(3k-1)=4k/(3k+2)求k
(4k^2+7k)+(-k^2+3k-1)
数学的增1法n=1.2=2.成立.设n=k时成立:(k+1)(k+2).(k+k)=1*3*...*(2k-1)*2^k.看n=k+1:左边=[(k+1)+1][(k+1)+2]……[(k+1)+(k+1)] =[(k+1)(k+2)……(k+k)](k+1+k)(k+1+k+1)/(k+1) =[1*3*...*(2k-
