Alrighty
remember

and
![x^\frac{m}{n}=\sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7Bm%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D)
and
![(x^m)^n=x^{mn} and [tex]x^0=1](https://tex.z-dn.net/?f=%28x%5Em%29%5En%3Dx%5E%7Bmn%7D%20and%20%5Btex%5Dx%5E0%3D1)
for all real numbers x
and

b.

=

c.
x^0=1
so
that (x^-3y)^0=1
because exponents first in pemdas
so we are left with
x^2y^-1
7.41% as a decimal is 0.0741. :)
Answer:
These are the answers...
Step-by-step explanation:
6 is a solution.
10 is not a solution.
-5 is a solution.
9 is a solution.
12.5 is not a solution.
0 is a solution.
49 divided by 33 is 1.48484848 so your answer would be the last one (49/33)
Hi there! Think of x as 2 and 6 and think of y as 8 and 12. 8-12/2-6=-4/-4. Now, -4/-4=1. Therefore, the answer is C. 1
