C = 1.(1.5.6) + 2.(1.5.6) + 4.(1.5.6) / 1.(1.3.5) + 2. (1.3.5) + 4.(1.3.5) + 9.(1.3.5)
C= 1.5.6.(1+2+4)/1.3.5(1+2+4+9)
C= 1.1.2.1/1.1.1.1
C=2/1
C= 2
Chúc bạn học tốt

C=(1.5.6+2.10.12+4.20.24+9.45.54)/(1.3.5+2.6.10+4.12.20+9.27.45)
C=(1.5.6+2.2.5.6.2+4.4.5.6.4+9.9.5.6.9)/(1.3.5+2.2.3.5.2+4.4.5.3.4+9.9.3.5.9)
C={5.6.(1+8+4+4+4+4+9+9+9)}/{3.5.(1+8+4+4+4+4+9+9+9)
C=(5.6)/(3.5)
C=2
Vậy C=2
