If `a=-9` and `b=-6` , show that (a-b)`ne`(b-a)

If a = -9 and b = -6, show that (a - b) = (b - a).

IF a=2/3 , b=(-5)/6 and c=7/d ,show that (a-b)-c ne a-(b-c)

If 2^(a)=3^(b)=6^(c) then show that c=(ab)/(a+b)

If a,b,c are in AP, than show that a^(2)(b+c)+b^(2)(c+a)+c^(2)(a+b)=(2)/(9)(a+b+c)^(3) .

If A={1,2} and B={2,3} , then show that: AxxB ne B xxA

If A and B are two events such that P(A) ne 0 and P(B) ne 1 then P((barA)/(B))

If a ne b ne c, "prove that" (a, a^(2)), (b, b^(2)), (0, 0) will not be collinear.

If A and B are two sets such that n(A)=7, n(B)=6and (A nnB)ne phi Then the greatest possible value of n (A Delta B) is

If A and B are two sets such that n(A)7, n(B),=6 and n(AnnB) ne phi The least possible value of n(A Delta B), is
