Simplify the radical

= 
= 
Square both sides
T² =
( multiply both sides by (g + f) )
T²(g + f) = Ufg ( distribute left side )
T²g + T²f = Ufg ← subtract Ufg from both sides
T²g - Ufg + T²f = 0 ← subtract T²f from both sides
T²g - Ufg = - T²f ← factor out g from each term on the left side
g(T² - Uf) = - T²f ← divide both sides by (T² - Uf)
g = -
= 
Answer:
D 6
Step-by-step explanation:
Normally when I multiply mixed numbers, I change them to improper fractions first so that it is easier.
1
× 5 =
× 5
Multiply 5 by the numerator of the fraction and leave the denominator alone.
× 5 =
Change back to simplest form.
= 6
