If `a^(2) +b +2a sqrtb =7+ 4sqrt3 and c^(2) +d -2csqrtd =1 ` then find the value of (a + b +c +d) .

If sqrta : sqrtb = sqrt3 : sqrt2 " and " sqrtb : sqrtc = sqrt3 : sqrt2 , then find the value of (sqrta + sqrtb ) : ( sqrtb + sqrtc) .

If A : B = 1 : 2, B : C = 3 : 4 and C : D = 5 : 6, then find the value of D : C : B.

If real numbers a, b, c, d, e satisfy a+1=b + 2 = c+ 3 = d + 4 = e + 5 = a + b + c + d + e + 3 then find the value of a^2 + b^2 + c^2 + d^2 + e^2

If a, b, c, d satisfy the equation a + 7b + 3c + 5d = 0 , 8a + 4b + 6c + 2d = - 16 , 2a + 6b + 4c + 8d =16 and 5a + 3b + 7c + d = -16 then the value of (a + d) (b + c) =______

For a real number a with 0 lt a lt (1)/(2) , if b = 1 - a + a^(2) - a^(3) + …, c = 1 - b + b^(2) - b^(3)+… and d = 1 + c + c^(2) +… , find the value of (d-a)

If 4/(1+sqrt2+sqrt3)=a+b sqrt2+c sqrt3-d sqrt6 , where a, b, c. d are natural numbers, then the value of a + b+ c + d is: यदि 4/(1+sqrt2+sqrt3)=a+b sqrt2+c sqrt3-d sqrt6 जहां a, b, c ,d प्राकृतिक संख्याएँ है, तो a+b+ c+ d का मान है:

If A : B = 2 : 3, B : C = 4 : 5 and C : D = 6 : 7, then the value of (A+B+C)/D is : यदि A : B = 2 : 3, B : C = 4 : 5 और C : D = 6 : 7 है, तो (A+B+C)/D का मान क्या होगा ?

Complete set of solution of inequation sqrt(3x^(2)+5x+7)-sqrt(3x^(2)+5x+2)>1 is (-a,-b)uu(-c,-d) then find the value of a +b+c+d
