Answer:
![10](https://tex.z-dn.net/?f=10)
Step-by-step explanation:
![\frac{2(10)^2(10-5)}{10(10)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%2810%29%5E2%2810-5%29%7D%7B10%2810%29%7D)
Square the 10.
![\frac{2(100)(10-5)}{10(10)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28100%29%2810-5%29%7D%7B10%2810%29%7D)
Subtract 10 with 5.
![\frac{2(100)(5)}{10(10)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28100%29%285%29%7D%7B10%2810%29%7D)
Multiply the numbers in the numerator.
![\frac{2(500)}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28500%29%7D%7B100%7D)
![\frac{1000}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1000%7D%7B100%7D)
Divide 1000 with 100.
![=10](https://tex.z-dn.net/?f=%3D10)
