Notice the x^-2, this is equal to 1/x^2. Then notice the y^0, any value raised to the zero power is equal to 1, ie n^0=1. So your expression is actually just:

8/x^2, the y value has no effect upon the output. They want you to evaluate, which must means calculate, the value when x=2 so:

8/(2^2)

8/4

2

How to solve x+9/5=5/3-x-3/6

Schach [20]

Answer:

x = $-\frac{19}{60}$

Step-by-step explanation:

$x + \frac{9}{5} = \frac{5}{3} - x -\frac{3}{6} \\x + x = \frac{5}{3} -\frac{3}{6} - \frac{9}{5} \\2x = \frac{50 - 15 - 54}{30} \\2x = \frac{-19}{30} \\x= \frac{-19}{30} / 2 = \frac{-19}{30} * \frac{1}{2} \\x= \frac{-19}{60}$
