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
