Answer» Answer: x 4 can be ACHIEVED in the following WAYS: x 4 .1 n−4 .(x 2 ) 0 .(x ) 0
Hence, coefficient will be n C 4 . x 2 .1 n−3 .(x 2 ) 1 .(x 3 ) 0
Hence, coefficient will be 3 n C 3 . x 1 .1 n−2 .(x 2 ) 0 .(x 3 ) 1
Hence, coefficient will be 2 n C 2 . x 0 .1 n−2 .(x 2 ) 2 .(x 3 ) 0
Hence, coefficient will be n C 2 . Hence, the required coefficient will be n C 4 +3 n C 3 +3 n C 2
= n C 4 +3( n C 3 + n C 2 ). = n C 4 +3( n+1 C 3 ). = n C 4 + n C 2 + n C 1 . n C 2 Step-by-step explanation: |

Find the nth and the sum of the first n term of progression 8,98,998,9998....in term of n. |
|
Answer» Answer: nth term = 10^n - 2 ; Sum of n terms = Step-by-step explanation: sequence : 8,98,998,9998 ... n terms this can be WRITTEN as : (10-2) , (100-2) , (1000-2) , (10000-2) ... 1st term = 10 - 2 2nd term = 100 - 2 = 10^2 - 2 3rd term = 10^3 - 2 so, nth term = 10^n - 2 sum of n terms = 8+98+998+9998+ ... = (10-2)+(100-2)+(1000-2)...n terms separating the terms, we get : S(n) = (10+100+1000+10000+....) - (2+2+2+2+...) we see, the first term is a geometric progression, with first term = 10, and ratio = 10 so, S(n) = sum of GP - 2(n) ->sum of GP : s(n) = a*(r^n-1) / (r-1) = 10*(10^n-1) / (10-1) = 10(10^n - 1) / 9 so we get : S(n) = |
