Question

Find the value of 1 /5 abc X (− 1/3 C²) X - 4b²c, when a = 1, b = 2 and c = 3.​

Answer 1

Answer:

19.2C² or 172.8

Step-by-step explanation:

If C is not equal to c

1/5abc*(-1/3 C²)(- 4b²c)

1/5*1*2*3*(-1/3*C²)(- 4*2*2*3)

6/5*(-1/3*C²)(-48)

(-288/5)(-1/3*C²)

19.2C²

If C is equal to c

1/5abc*(-1/3 C²)(- 4b²c)

1/5*1*2*3*(-1/3*3*3)(- 4*2*2*3)

6/5*(-3)(-48)

864/5

172.8
