can someome explain this pls...

|r| = always positive

|r|* s = r^2

lets assume s = (-2)^2 and r = - 4

is this case

1)rs = -16 False

2) r=s False

3) s ≥ r True

So option c

Hi...

\(|r|*s=r^2\)..

Now |r| and r^2 are always positive..

So positive*s=positive

Here s has to be positive

So two points

1) s is positive and r can be anything

2) numeric value of s and r is equal that is |r|=|s|

If r is negative, s>r and if r is positive, s=r

Thus s can never be <r
