If |a| = 3, |b| = 4 and |a + b| = 1, then |a - b| =

If |a|=|b|=1 and |a+b|=sqrt(3) , then the value of (3a-4b)(2b+5b) is

If a:b = 3:4, then 4a:3b = 1:1.

If a+b+c=0 and a^2+b^2+c^2=1, then (a) a b+b c+c a=1/2 (b) a b+b c+c a=-1/2 (c) a^4+b^4+c^4=1/2 (d) a^4+b^4+c^4=3/2

If A = {1, 2, 3} , B = {3, 4, 5} , then find A- B and B - A .

Find A × B, A × A and B × A : A = {1, 2, 3} and B = {1, −4} .

Find the product of (3a + 4b) and (3a - 4b) and verify it when a = -1 and b = 1 .

If a : b : c =1/4:1/3:1/2 , then a/b : b/c: c/a =? यदि a : b : c =1/4:1/3:1/2 , तो a/b : b/c: c/a =?
