Answer:
x = 4
Step-by-step explanation:
To solve, simplify the expression then use inverse operations to isolate x.

F(x) = 4 [cos (x)]^2 - 3 = 0
4[cos(x)]^2 = 3
cos(x) = √3 / 2
That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.
Answer: x = 30 degrees and x = 330 degrees
4.3 x 10 to the power of 2
