Hello
Sir 70th number question smjh nhi aaya, thoda confusion h.....
Sir standard form me dolve krne par...
(A+B+C)(A+B+C')(A+B+C)(A+B'+C)(A+B'+C')(A'+B'+C')(A+B+C)(A+B'+C)
isme (A+B+C) 3times hai, 1st (A+B+C) and 2nd (A+B+C) ko one times hi likhenge...bcz 1.1=1 hoga, and 3rd (A+B+C) cancel out ho jayega bcz isme ek jgh (A'+B'+C') bhi h...and 1.0=0 hota h.
Aur isme (A+B'+C) bhi 2 times aaya h to...ise 1 times hi likhenge....is trh hare paas jo bachega wo yehona chahiye n Sir......
(A+B+C')(A+B+C)(A+B'+C')(A+B'+C)
