Answer:
8r^4
Step-by-step explanation:
√(64r^8) = √((8r^4)^2) = 8r^4
_____
You can make use of either or both of these rules of exponents:
(a^b)^c = a^(b·c) . . . . . used above
![\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Using the second rule, you can write the expression as ...

Given:
In
.
To find:
The list of angles in order from least to greatest.
Solution:
In a triangle, the sides of triangles are completely depend on the interior of the triangle. In the triangle, the longest side has the largest opposite angle and the shortest side has the smallest opposite angle.
Arrange the sides of the triangle ACR in ascending order.


It means the order of the opposite angles to sides is:

Therefore, the list of angles in order from least to greatest is
.
The biggest common factor number is the GCF number. So the greatest common factor 55 and 65 is 5.
