Find the domain of definition of the following `f(x)` given by `f(x)=log_4{(log_(5)log_3(18 x-x^2-77)}`

Explanation

We know that for domain in `logx` x>0

So,let `18x−x^2−77=A ,`

` log_3​(18x−x^2−77)=B `

` log_5​(log_3(18x−x^2−77))=C`

Thus, we need that `A>0 ,B>0 , C>0`

For `A`

`18x−x^2−77>0`

`xϵ(7,11)`
