Work: Calculate the value of equation C(5,2)*C(3,2)*C(1,1)-2*C(2,2)*C(3,2)*C(1,1) .
Question type: Mathematical calculation
Solution:
C(5,2)*C(3,2)*C(1,1)-2*C(2,2)*C(3,2)*C(1,1)
=10*C(3,2)*C(1,1)-2*C(2,2)*C(3,2)*C(1,1)
=10*3*C(1,1)-2*C(2,2)*C(3,2)*C(1,1)
=10*3*1-2*C(2,2)*C(3,2)*C(1,1)
=10*3*1-2*1*C(3,2)*C(1,1)
=10*3*1-2*1*3*C(1,1)
=10*3*1-2*1*3*1
=30*1-2*1*3*1
=30-2*1*3*1
=30-2*3*1
=30-6*1
=30-6
=24
Answer:C(5,2)*C(3,2)*C(1,1)-2*C(2,2)*C(3,2)*C(1,1)=24
