Answer with Step-by-step explanation:

We have to find the excluded value for expression for:

[tex]\dfrac{(x-4)^2}{(x-9)^2}[/tex]

for the above expression to be well defined the denominator can't be zero

i.e.  (x-9)^2≠0

i.e. x-9≠0

i.e. x≠9

Hence, the excluded value for the expression [tex]\dfrac{(x-4)^2}{(x-9)^2}[/tex] is:

9

Answer:

The answer is D, 9
