Question

If a is an integer, which of the following is always true.

Answer 1

Answer:

Given:

a is an integer

To find:

Which of the following is always true (a) lal =a (b) lal<a (c)lal >a

Solution:

| | - mod represents an absolute value of an entity.

When we remove mod, it results in two possible values, negative and positive.

Therefore, for an integer "a" we get "+ a" and "- a" after removing mod.

∴ + a ⇒ |a| > a

∴ - a ⇒ |a| < a
