Given :

pashok25 [27]

$\\ \sf\longmapsto A=(1-4)-(2+1)$

$\\ \sf\longmapsto A=-3-3$

$\\ \sf\longmapsto A=-6$

$\\ \sf\longmapsto B=(3-\dfrac{1}{2})-(2-4)$

$\\ \sf\longmapsto B=\left(\dfrac{5}{2}\right)+2$

$\\ \sf\longmapsto B=\dfrac{5+4}{2}$

$\\ \sf\longmapsto B=\dfrac{9}{2}$

Now

$\\ \sf\longmapsto AB=-6\times \dfrac{9}{2}$

$\\ \sf\longmapsto AB=-3(9)$

$\\ \sf\longmapsto AB=-27$

$\\ \sf\longmapsto \dfrac{9}{2}\times (-6)$

$\\ \sf\longmapsto 9(-3)$

$\\ \sf\longmapsto -27$

Observed:-

$\\ \sf\longmapsto AB=BA$
