यदि `a+b+c+d=4` हो तो `1/((1-a)(1-b)(1-c))+1/((a-d)(1-a)(1-b))` का मान बताइए?

If a+ b+c + d = 4 then the value of 1/((1-a) (1-b) (1-c)) + 1/((1-b) (1-c) (1-d)) + 1/((1-c)(1-d)(1-a)) + 1/((1-d)(1-a) (1-b)) is

If a+b+c+d=4 then the value of (1)/((1-a)(1-b)(1-c))+(1)/((1-b)(1-c)(1-d))+(1)/((1-c)(1-d)(1-a))+(1)/((1-d)(1-a)(1-b)) is

If a + b + c + d = 2, then the maximum value of (1 + a)(1 + b)(1 + c)(1 + d) is_____. यदि a+ b+ c+ d = 2, तो (1+ a)(1+b)(1+ c)(1+ d) का अधिकतम मान_____है।

If 3a = 27b = 81c and abc = 144, then the value of 12(1/a+1/(2b)+1/(5c)) is : यदि 3a = 27b = 81c है तथा abc =144 है, तो 12(1/a+1/(2b)+1/(5c)) का मान क्या होगा ?

If a:b:c=1:3:5, what is the value of (4a-b+2c)/(3(a+b+c)) ? यदि a:b:c=1:3:5 है, तो (4a-b+2c)/(3(a+b+c)) का मान क्या होगा ?

If b+c = ax, c+a = by and a+b = cz, then the value of 1/9[1/(x+1)+1/(y+1)+1/(z+1)] is : यदि b+c = ax, c+a = by तथा a+b =cz है, तो 1/9[1/(x+1)+1/(y+1)+1/(z+1)] का मान क्या होगा ?

If a-(1//a) = b, b-(1//b) =c and c - (1//c) = a , then what is the value of (1//ab) + (1//bc) + (1//ca) ? यदि a-(1//a) = b, b-(1//b) =c तथा c - (1//c) = a है, तो (1//ab) + (1//bc) + (1//ca) का मान क्या है?
