The value of `(10^11 - 10^9 - 2 xx 11 * 10^8 - 3 xx 11^2 xx 10^7 - ..... - (10) xx 11^9)` is equal to

The value of (10^(11)-10^(9)-2xx11*10^(8)-3xx11^(2)xx10^(7)-....-(10)xx11^(9)) is equal to

[(-10)xx(-9)]+(-10) is equal to

If (10)^9 + 2(11)^1 (10)^8 + 3(11)^2 (10)^7+..+10(11)^9 = k(10)^9 then k is equal to :

If (10)^(9) + 2 (11)^(1) (10)^(8) + 3(11)^(2) ( 10)^(7) + …. =k ( 10)^(9) , then k is equal to

If (10)^9 + 2(11)^1 (10)^8 + 3(11)^2 (10)^7+...........+10 (11)^9= k (10)^9 , then k is equal to :

If (10)^9 + 2(11)^1 (10)^8 + 3(11)^2 (10)^7+...........+10 (11)^9= k (10)^9 , then k is equal to :

If (10)^(9) + 2(11)^(1) (10)^(8) + 3(11)^(2) (10)^(7) + …. + 10(11)^(9) = k(10)^(9) , then k is equal to

11/2 xx 3/10 =_____

Let's from the numbers from their expanded from given below:- 8 xx 10^4 + 2 xx 10^3 + 3 xx 10^2 + 6 and 9 xx 10^4 + 5 xx 10^3 + 6 xx 10^2 + 7 xx 10

if 10^(9)+2*11^(1)*10^(8)+3*11^(2)*10^(7)+............+10*11^(9)=k*10^(9) then k equals to:
