Given:

The expression can be used to express powers and roots together.
Here, we can rewrite this as:
![x^{\frac{m}{n}}=\sqrt[n]{x^m}\text{ = (}\sqrt[n]{x})^m](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D%5Ctext%7B%20%3D%20%28%7D%5Csqrt%5Bn%5D%7Bx%7D%29%5Em)
Here, m is the power while n is the root.
Therefore, m represents the power to which x is raised while n represents the root that is being taken.
ANSWER:
Power; Root
Answer:
0.8944
Step-by-step explanation:
Use a calculator or table.
Using a z-score table:
P(z < 1.25) = 0.8944
4x+2y=10 Equation 1
x-y=13 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=y+13
Substitute value of x in equation 1
4(y+13)+2y=10
4y+52+2y=10
6y+52=10
6y=-42
y=-7
Now substitute value of y in x=y+13
x=-7+13
x=6
Answer: (6,-7)
