To simplify this expression, we will use the properties of logarithms:

2log(7)32 = log(7)(32^2) = log(7)10242log(7)14 = log(7)(14^2) = log(7)196log(7)256 = log(7)(256) = 4

Now, we can rewrite the expression using the simplified logarithms:

log(7)1024 - log(7)196 - log(7)256 = log(7)(1024/196) - 4

Calculating the value inside the logarithm gives:

log(7)(5.224) - 4

Therefore, the simplified expression is: log(7)(5.224) - 4
