Answer:

The largest value is 10.56

Step-by-step explanation:

We are given to find the largest value of

[tex]Z=a.Bc+0.D[/tex]

so, 'a' must be largest value among them

and we have select from 1 to 9

so, a=9

since, B and D are at same places

so, we can have largest value

B=8

D=7

now, we can select next highest value

c=6

now, we can plug these values

[tex]Z=9.86+0.7[/tex]

[tex]Z=10.56[/tex]
