Answer:

Step-by-step explanation:
The last one is also the answer
Using the rational exponet rule,
![\sqrt[n]{ {x}^{m} } = x {}^{ \frac{m}{n} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7B%20%7Bx%7D%5E%7Bm%7D%20%7D%20%20%3D%20x%20%7B%7D%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20)
Using this number,

40 is the base so it will stay same. Remember this is a square root sign so our nth root is 2 so our denominator if the rational exponet is 2.

so our numerator is 1 so

A) rhombus
b) trapezoid
c) square
d) rectangle
e) parallelogram
f) trapezoid
g) a parallelogram has 4 sides. The two opposite sides are always parallel.
A trapezoid has 4 sides. Only two opposite sides are parallel. The other two sides are not parallel.
h) a square has angles that must be 90degree big. A rhombus doesn’t.
