Step-by-step explanation:
1) 117×99
= ( 100+17)×99 = 99×100 + 99×17
= 9900 + 1683
= 11583
2) 8126×169-8126×69
= (169-69)×8126
= 100×8126=812600
3) 105×168
= (100+5)×168
= 100×168+168×5
= 16800+840 =17640
4) 77×96
=(70+7)×96=70×96+7×96
=6720+672=7392
5) 2100×102-2100×2
= (102-2)×2100
= 100×2100
= 210000
6) 17×23 = (10+7)×23
= 10×23+7×23
= 230+161
= 391
7) 887×461-887×36
=(461-36)×887
=425×887
= 376975
