11!/8!=990 6!=46656. Sir g yaha app na bhola k highest number k bd jho number os ko multiply karay. Highest number ka mtlb agr hm تعداد lai pr bhi tikh ha. For example.how many words are formed from a,b,c,d تعداد =4 4!=4×3×2×1=24

Sir ages par video upload kardein❤

n!=n(n-1)! n!/n =( n-1)! orr (n-1)!=n!/n put n = 1 (1-1)!=1!/1 (0)!=1 0!=1 hence proved

Sir!You are not clarifying.! when the examiner gives the question: How many 3 digits can be formed from 21, 22, 23, 24, 25, 26? then the right answer is actually 6 × 5 × 4. not 26 × 25 × 24 because we need to multiply the highest quantities, not the highest numbers.
