Given:
The expressions are


To find:
The simplified form of each expression.
Solution:
We have,

![[\because x^{-n}=\dfrac{1}{x^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20x%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Bx%5En%7D%5D)

Therefore, the simplified form of
is
.

The answer is actually $17.821. I just took the test.
If you cut a triangle out of a piece of paper, and move that triangle around (sliding, rotating, reflecting) then that triangle will retain its original shape and size. The three movement types mentioned are rigid motions. They do not change the size or shape of the triangle. If two triangles are congruent, then a sequence of one or more rigid motions can be applied to have them line up together.
