If a+b+c+d=4 then find the value of 11-a1-b1-c+11-b1-c1-d+11-c1-d1-a+11-d1-a1-b
Find the value of the given expression
To find the value of given expression, we first take the LCM of all denominators and cross multiply.
We get,
11-a1-b1-c+11-b1-c1-d+11-c1-d1-a+11-d1-a1-b=1-d+1-a+1-b+1-c1-a1-b1-c1-d
=4-(a+b+c+d)1-a1-b1-c1-d
As it is given that a+b+c+d=4
. 11-a1-b1-c+11-b1-c1-d+11-c1-d1-a+11-d1-a1-b=4-41-a1-b1-c1-d
∴ 11-a1-b1-c+11-b1-c1-d+11-c1-d1-a+11-d1-a1-b=0
Hence, the value of given expression is 0.
