√27w^8

Answer 1

\[=\sqrt{27w^8}=(27w^8)^{\frac{1}{2}}=(3^3w^8)^\frac{1}{2}=3w^4 \sqrt3\]

Answer 2

Let g and f be two functions defined by
g(x)=5-4x^2

f(x)=9-5x

for any real number .
Find g/f(-5) and then find all values that are NOT in the domain of g/f . If there is more than one value, separate them with commas.
