Question

What is the sum of a-1/abc^3 + 3-b/abc^3

Answer 1

The answer is
`(a-b+2)/(abc^(3) )`

The expression is
`(a-1)/(abc^(3) ) + (3-b)/(abc^(3) )`

Since
`(a)/(x) + (b)/(x) = (a+b)/(x)`, then:


`(a-1)/(abc^(3) ) + (3-b)/(abc^(3) ) = (a-1+3-b)/(abc^(3) )= (a-b-1+3)/(abc^(3) )=(a-b+2)/(abc^(3) )`
