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).
log(3) = log(12/4)
Use the quotient rule [ ] to simplify.
log(12/4) = log(12) - log(4)
Simplify using the given values for 12 and 4.
1.079 - 0.602
0.477
Therefore, log(12) ≈ 0.477
Best of Luck!
