Answer:
The given expressions simplifies to tan (4x).
Step-by-step explanation:
Here, the given expression is : 
By TRIGONOMETRIC IDENTITY:
Putting this identity here, and taking A = 9 x, B = 5 x, we get
= tan(4x)
Hence, the given expressions simplifies to tan (4x).
The answer is 18, Hope you get it right!
