0(a-B)^(2)=

if A=[[3,-41,12,0]] and B=[[2,1,21,2,4]] then verify (BA)^(2),!=B^(2)A^(2)

The statement (a+ib)<(c+id) is true for a^(2)+b^(2)=0( b) b^(2)+d^(2)=0b^(2)+c^(2)=0(d) None of these

If the roots of ax^(2)+bx+c=0 are real and equal then ………….. A) b^(2)-4ac lt 0 B) b^(2)-4ac=0 C) b^(2)-4ac gt 0 D)cannot say

If a lt 0 and b lt 0 , then (a +b)^(2) gt 0 .

If a+b+c=0&a^(2)+b^(2)+c^(2)=1 then the value of a^(4)+b^(4)+c^(4) is

[((a^(0)+b^(0))(a^(0)-b^(0)))/(a^(2)-b^(2))]^(0^(+^(5)))" "("where "a ne 0 and b ne 0) is

If the points (a^(2), 0),(0, b^(2)) and (1,1) are collinear then

If points (a^(2),0),(0,b^(2)) and (1,1) are collinear,then
