Answer:
![-a^{2}](https://tex.z-dn.net/?f=-a%5E%7B2%7D)
Step-by-step explanation:
![\frac{-1}{a^{-2} } = \frac{-1}{\frac{1}{a^{2} } } = -1 * \frac{a^{2} }{1} = -a^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7Ba%5E%7B-2%7D%20%7D%20%3D%20%5Cfrac%7B-1%7D%7B%5Cfrac%7B1%7D%7Ba%5E%7B2%7D%20%7D%20%7D%20%3D%20-1%20%2A%20%5Cfrac%7Ba%5E%7B2%7D%20%7D%7B1%7D%20%20%3D%20-a%5E%7B2%7D)
Answer:
A)4
Step-by-step explanation:
Assuming all edges are integral values
The most basic right angles triangle with integral edges is
(3,4,5)
as it obeys pythogores theorem
which is
![a^{2}+ b^{2} =c^{2} \\\text{where c is the hypotenuse}\\\text{and a and b are the other side}](https://tex.z-dn.net/?f=a%5E%7B2%7D%2B%20b%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%5C%5C%5Ctext%7Bwhere%20c%20is%20the%20hypotenuse%7D%5C%5C%5Ctext%7Band%20a%20and%20b%20are%20the%20other%20side%7D)
![3^{2} +4^{2} =5^{2}](https://tex.z-dn.net/?f=3%5E%7B2%7D%20%2B4%5E%7B2%7D%20%3D5%5E%7B2%7D)
Now, double each edge,it will still remain a right angled triangle since it will still obey pythogores theorem
so the edges are (4,6,10)
⇒4 cm is the short leg of a integral right triangle with hypotenuse 10 cm
