What is the sum of the reciprocal of 1/-13 and the reciprocal of -1/2

murzikaleks [220]

Answer:

-15

Step-by-step explanation:

1/-13

The reciprocal is

$1/ 1/-13$

Because of the law of indices,

We'll have $1 * -13$

= -13.

-1/2

The reciprocal is

1 ÷ -1/2

Because of the law of indices,

We'll have $1 * -2$

= -2

Therefore, the sum would be -13 + (-2) which would be equals to -15.
