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
