Answer: 
Step-by-step explanation:
When you add fractions with different denominators, you need to find the Least common denominator (LCD):
Descompose the denominators (5 and 15) into its prime factors and then choose the commons and non-commons with the highest exponents:

Divide the LCD by each original denominator of each fraction and multiply the result by each original numerator of each fraction. After this, you can add the numerators and reduce the fraction.
Then:

The correct option is;
The ranges of f(x) and h(x) are similar and different from the ranges of g(x)
Step-by-step explanation:
Here we have the functions given as follows;
f(x) = -6/11 (11/2)ˣ
g(x) = 6/11 (11/2)⁻ˣ
h(x) = -6/11 (11/2)⁻ˣ
from the above equations, it can be seen that f(x) and h(x) are always negative while g(x) is always positive
f(x) and h(x) are symmetric about the y axis while g(x) and h(x) are symmetric about the x axis
Also h(x) is the inverse of f(x) hence the ranges of f(x) and g(x) are similar and are different from the ranges of g(x).

Steps-
= s * 3st1/3
= 3s^2t1/3
= 1*3s^2t / 3
= 32^2t / 3
= s^2t
The final answer is B) s^2t
