If r@s=s@r which of the following can define the equation?
1. r@s=r+s-rs
2. r@s=(r+s)(r-s)
3. r@s =r/s+ s/r
1. r@s=r+s-rs
2. r@s=(r+s)(r-s)
3. r@s =r/s+ s/r
If r@s=s@r which of the following can define the equation?
1. r@s=r+s-rs
s@r = s+r -sr
Correct
2. r@s=(r+s)(r-s)
s@r = (s+r)(s-r)
Wrong
3. r@s =r/s+ s/r
s@r = s/r + r/s
Correct
