![(2x^{2} )(3x^{6} ) = 6x^{8}](https://tex.z-dn.net/?f=%282x%5E%7B2%7D%20%29%283x%5E%7B6%7D%20%29%20%3D%206x%5E%7B8%7D)
![\frac{25x^{6} y^{6} }{5x^{4} y^{3}} = 5 x^{2} y^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B25x%5E%7B6%7D%20y%5E%7B6%7D%20%20%7D%7B5x%5E%7B4%7D%20y%5E%7B3%7D%7D%20%3D%205%20%20x%5E%7B2%7D%20%20%20%20y%5E%7B3%7D)

![6x^{2} x^{6}](https://tex.z-dn.net/?f=6x%5E%7B2%7D%20x%5E%7B6%7D)
When same variables are multiplied their powers are added
![6x^{2+6}](https://tex.z-dn.net/?f=6x%5E%7B2%2B6%7D)
