Question

find the sum of additive inverse and multiplicative inverse of minus 5 by 9​

Answer 1

Step-by-step explanation:

Additive inverse of 59 is −59 and multiplicative inverse of 59 is 95

Explanation:

Additive inverse of a number is the number which when added to it makes the sum zero 0 - the additive identity element . Observe that 0 is known as additive identity element as when this is added to any number, it results in the same number.

Obviously additive inverse of x is −x and hence additive inverse of 59 is −59.

Multiplicative inverse of a number is the number which when multiplied to it makes the product one 1 - the multiplicative identity element . Observe that 1 is known as multiplicative identity element as when this when multiplied to any number, results in the same number.

Obviously multiplicative inverse of x is 1x and hence additive inverse of 59 is 159=95.
