Question

If. A, B and C are rational numbers, the condition to satisfy is, A-CB-C) = (A-B)-C Eg: 1/2-3/4-2/3 in associative property under subtraction. A=1/2, B=3/4, C=2/3?​

Answer 1

$\huge\pink{\boxed{\green {\mathbb{\overbrace {\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{answer }}}}}}}}}$

AB=(3−2)2+(4+1)2=1+25=26

BC=(−2−3)2+(3−4)2=25+1=26

CD=(−3+2)2+(−2−3)2=1+25=26

DA=(−3−2)2+(−2+1)2=25+1=26 

AC=(−2−2)2+(3+1)2=16+16=32 

BD=(−3−3)2+(−2−4)2=36+36=72

Answer 2

AB=(3−2)2+(4+1)2=1+25=26

BC=(−2−3)2+(3−4)2=25+1=26

CD=(−3+2)2+(−2−3)2=1+25=26

DA=(−3−2)2+(−2+1)2=25+1=26

AC=(−2−2)2+(3+1)2=16+16=32

BD=(−3−3)2+(−2−4)2=36+36=72
