Answer 1

Answer:

Given expression is x+

x

1

.

We know that, additive inverse means an addition of a term or expression to the given expression, such that their sum equals to zero.

Let P be such an expression.

Hence, x+

x

1

+P=0

⇒P=−x−

x

1

.

Hence, the additive inverse of x+

x

1

is −x−

Answer 2

Answer:

the additive inverse of 2 is −2

the multiplicative inverse of 2 is 2/1

the sum of the additive and the multiplicative inverse is

=−2+ 2/1

= 2−3
