If (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5, then (3a + 5b) : (9a - 2b)=? यदि (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5 है, तो (3a + 5b) : (9a - 2b)=?

If a^3-b^3=1603 and (a-b)=7, then (a+b)^2 -ab is equal to: यदि a^3-b^3=1603 तथा (a-b)=7, तो (a+b)^2 -ab का मान किसके बराबर होगा ?

If (5a - 3b) : (4a - 2b) = 2:3, then a:b is equal to: यदि (5a - 3b) : (4a - 2b) = 2:3 है, तो a : b का मान क्या होगा ?

If a = (sqrt5 + 1)/(sqrt5 + 1) and b = (sqrt5 -1)/(sqrt5 + 1) , then find the value of (a) (a^(2) + ab + b^(2))/(a^(2) - ab + b^(2)) (b) ((a -b)^(3))/((a + b)^(3)) (c) (3a^(2) + 5ab + b^(2))/(3a^(2) - 5ab + b^(2)) (d) (a^(3) + b^(3))/(a^(3) - b^(3))

If a^3+b^3=110 and a+b=5, then (a+b)^2 -3ab is equal to: यदि a^3+b^3=110 तथा a+b=5, तो (a+b)^2 -3ab का मान क्या होगा ?

If a^(3)-3a^(2)+5a-17=0 and b^(3)-3b^(2)+5b+11=0 are such that a+b is a real number, then the value of a+b is
