If `a/b=4/5` and `b/c=(15)/(16)` , find the value of `(c^2-a^2)/(c^2+a^2)` .

If (a)/(b)=(4)/(5) and (b)/(c)=(15)/(16), then (c^(2)-a^(2))/(c^(2)+a^(2)) is (a) (1)/(7)( b) (7)/(25)( c) (3)/(4) (d) None of these

If (a)/(b)=(4)/(5) and (b)/(c)=(15)/(16) then (18c^(2)-7a^(2))/(45c^(2)+20a^(2)) is equal to यदि (a)/(b)=(4)/(5) और (b)/(c)=(15)/(16) तो (18c^(2)-7a^(2))/(45c^(2)+20a^(2)) का मान है -

If (a)/(b)=(4)/(5)and(b)/(c)=(15)/(16) then (c^(2)-a^(2))/(c^(2)+a^(2)) would be (1)/(7) b.(3)/(4) c.(7)/(25) d.none of these

If a+b+c=0 and a^(2)+b^(2)+c^(2)=16, find the value of ab+bc+ca

If a+2b+3c=4, then find the least value of a^(2)+b^(2)+c^(2)

If a=2,b= -11 , c = 15 , find the value of b^(2)- 4ac .

If a+b+c=15 and a^(2)+b^(2)+c^(2)=83 find the value of a^(3)+b^(3)+c^(3)-3abc

If a+b+c=15 and a^(2)+b^(2)+c^(2)=83 find the value of a^(3)+b^(3)+c^(3)-3abc

If a = 2 , b = -2 and c = 2 , then find the value of a^2b + b^2c + c^2a

If a+b+c=0 , find the value of (a^2)/((a^2-b c))+(b^2)/((b^2-c a))+(c^2)/((c^2-a b)) (a) 0 (b) 1 (c) 2 (d) 4
