Is the set \mathbb{Z} a group under the operation a*b = a - b + ab ? Justify your answer.

Daniel [21]

Answer:

Step-by-step explanation:

Given that *is the binary operation in the sets of integers.

$a*b = a - b + ab$

closure: a-b+ab is again an integer belongs to Z. Hence closure is true.

Associativity: $a*(b*c) = a*(b+c-bc)\\= a-b-c+bc+ab+ac-abc\\= a-b-c +ab+bc+ca-abc$

$(a*b)*c=(a+b-ab)*c\\=a+b-ab-c+ac+bc-abc\\$

The two are not equal. Hence this cannot be a group as associtiavity does not hold good.

The bisector of an obtuse angle forms:acute anglesright anglesobtuse anglesstraight angles

Lerok [7]

It forms an acute angle.

The obtuse angle is greater than 90 degrees but less than180 degrees. So if a bisector is introduced, the resulting angle is acute. An acute is less than 90 degrees.
