F(x)=square root of x^2+24x+144. g(x) = square root of x^3 -216
Triss [41]

Answer:

Step-by-step explanation:

x^2 + 24x + 144 is a perfect square:  (x + 12)².  The square root of this is

±(x + 12).

g(x) = square root of x^3 -216 = √(x^3 - 216), or

√(x³ - 6³).   x³ - 6³ is not a perfect square, altho' it can be factored.
