The power rule (or law of indices) related to root is given
![x^{ \frac{1}{2} }= \sqrt[2]{x}](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%3D%20%20%5Csqrt%5B2%5D%7Bx%7D%20%20)
We have

Rewrite according to the rule we have

The exponent on y is '1'
The equilateral triangles will form a rhombus.
