If in the expansion of (a-2b)^(n) , the sum of 5^(th) and 6^(th) terms is 0, then th e values of a//b =

If in the expansion of (a-2b)^(n) , the sum of 5^(th) and 6^(th) terms is 0, then the values of a/b is

If in the expansion of (a-2b)^(n) , the sum of 5^(th) and 6^(th) terms is 0, then the values of a/b is (a) (n-4)/(5) (b) (2(n-4))/(5) (c) (5)/(n-4) (d) (5)/(2(n-4))

If in the expansion of (a-2b)^(n) ,the sum of 5th and 6 th terms is 0, then the values of a/b=(n-4)/(5) b.(2(n-4))/(5) c.(5)/(n-4) d.(5)/(2(n-4))

If in the expansion of (a-2b)^n , the sum of 5th and 6th terms is 0, then the values of a/b a. (n-4)/5 b. (2(n-4))/5 c. 5/(n-4) d. 5/(2(n-4))

In the binomial expansion of (a-b)^n, n ge 5 , the sum of 5th and 6th terms is zero, then

If in the expansion of (a+b)^(n) the coefficient of 4^(th) and 13^(th) term are equal.Find the value of n

In the binomial expansion of (a-b)^(n),nge5, the sum of 5th and 6th terms is zero then a/b equals:

Let n ge 5 b ne0, if in the binomial of (a-b)^(n), the sum of the 5th and 6th terms is zero, then the value of a/b is-
