Question 450399
If *[tex  f(c) = \sqrt{12}] and *[tex g(x) = \sqrt{3}] and you didn't typo, evaluating any expression should be simple. If the functions are constant, then anywhere you see an f of something (regardless of whether this "something" is an integer, a complex number, a quaternion, etc.), you can replace with *[tex \sqrt{12}] and anywhere you see a g, you can replace with *[tex \sqrt{3}]. For example,


*[tex \LARGE f(f(\ln{3.6 + 6i}))g(\zeta{(2)}) = \sqrt{12}\sqrt{3} = \sqrt{36} = 6]
