40 because the three in the units place is smaller than 5 so you round down.
Answer:
The simplified value of
is
.
Step-by-step explanation:
As the given expression is

Lets simplify this expression step by step
As
![-25^{-\frac{1}{2}}....[A]](https://tex.z-dn.net/?f=-25%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D....%5BA%5D)


So, lets plug
in equation [A] i.e. ![-25^{-\frac{1}{2}}....[A]](https://tex.z-dn.net/?f=-25%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D....%5BA%5D)
![-25^{-\frac{1}{2}}....[A]](https://tex.z-dn.net/?f=-25%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D....%5BA%5D)
∵ 
∵ 
Therefore, the simplified value of
is

Answer:
Option A is correct.
Step-by-step explanation:
The first step in the construction of a square inscribed in a circle is to draw a diameter of the circle.
Then we have to draw perpendicular bisector of the diameter using a compass.
Therefore, the perpendicular bisector will be another diameter of the circle and both the diameters will meet at the center of the circle.
Now, join the points with straight lines in order where the two diameters meet the circle. And finally, we will get a square inscribed in the circle.
Hence, option A is correct. (Answer)
Place is hundred thousand
