Ahh yes, negative exponents always give us a scare once and a while. All the negative means is to flip the position of its base. For instance, if x has a negative exponent and x in the denominator, all you would have to do is move x to the numerator with the same power (except it's no longer negative). Before we substitute x and all the other variables which the values given, let's eliminate the negatives first.
After flipping positions/eliminating the negative exponents it should look like this:

which simplifies to

now that everything is simplified, and all negative exponents are eliminated we can substitute x with 2, and y with (-4).

which simplifies to

Final Answer: - \frac{1}{32} [/tex]
A cross-section is the shape that would be exposed when cutting straight through a 3-D object. for example, cutting horizontally through a regular cone would expose a circle.
an intersection is where 2 or more shapes (does not matter how many dimensions) overlap. for example, the point at which two lines overlap is the intersection. or the area that two overlapping circles share is the intersection.
Answer:
The answer is
.
Step-by-step explanation:
This is because when you multiply them together you get
,
,
, and 
When you add the like terms you get,

Hello.
Since 3 < pi < 4,
√9 < pi √16
In fact, since pi^2 = 9.86,
<span>√9 < pi < √10.
Which means the you</span><span> can find pi between square roots √9 and √10.
