Question

Given 4c+5≠0 and c is a real number, what is the multiple inverse of 4c+5?

Answer 1

`(1)/(4c+5).`

Explanation:

The multiplicative inverse of a fraction
`(a)/(b)` is fraction
`(b)/(a).` For the multiplicative inverse of a real number, divide 1 by the number.

In your case, if
`4c+5\\eq 0` and c is a real number, the multiple inverse of 4c+5 is

`(1)/(4c+5).`

It s correctly defined, because the denominator of the fraction never turns into 0.
