- यदि a^(2) +b^(2)+c^(2)-ab-bc-ca=0 , तो
Text Solution
|
- यदि a+b+c=0 , तो (a^(2))/(bc)+(b^(2))/(ca) +(c^(2))/(ab)=
Text Solution
|
- यदि a^(1/3) +b^(1/3) +c^(1/3)=0 , तो
Text Solution
|
- यदि a+b+c=9 , तो ab+bc+ca=23 तो a^(2) + b^(2) +c^(2)
Text Solution
|
- यदि a+b+c = 9 , तथा ab+bc +ca = 23 तथा a^(3) + b^(3) +c^(3) - 3ab...
Text Solution
|
- (a-b)^(3) +(b-c)^(3) +(c-a)^(3) =
Text Solution
|
- ((a^(2)-b^(2))^(3)+(b^(2)-c^(2))^(3)+(c^(2)-a^(2))^(3))/((a-b)^(3)+(b-...
Text Solution
|
- (a+b)(a-b)(a^(2)-ab+b^(2))(a^(2)+ab+b^(2))=
Text Solution
|
- यदि a/b+b/a=-1 हो , तो a^(3) - b^(3) =
Text Solution
|
- (x^(2) -1) (x^(4) +x^(2) +1) =
Text Solution
|
- यदि a-b=-8 तथा ab=-12 हो , तो a^(3)-b^(3) का मान होगा ।
Text Solution
|
- यदि a/b+b/a=1 हो , तो a^(3)+b^(3) का मान होगा :
