Answer» ANSWER: -1/2+[(-4/3+3/7]=[(-1/2)+3/7]+(-4/3) -1/2+[(-28/21+9/21)] = [-7/14+6/14] +(-4/3) -1/2+[-19/21] = [-1/14]+(-4/3) -1/2-19/21 = -1/14-4/3 -21/42-38/42 = -3/42-56/42 -59/42 = -59/42

Q3} Verify that : a) -1/2+[(-4/3)+3/7]and [(-1/2)+3/7]+(-4/3) are there same .

Answer»

ANSWER:

-1/2+[(-4/3+3/7]=[(-1/2)+3/7]+(-4/3)

-1/2+[(-28/21+9/21)] = [-7/14+6/14] +(-4/3)

-1/2+[-19/21] = [-1/14]+(-4/3)

-1/2-19/21 = -1/14-4/3

-21/42-38/42 = -3/42-56/42

-59/42 = -59/42
