Question

Which statement about his product must be true

Answer 1

Option (3)

Explanation:

a, b, c, and d are the polynomials in which b and d are the non zero elements.

`(a)/(b)* (c)/(d)` =
`(a.c)/(b.d)`

a.c = Multiplication of two polynomials = Polynomial

b.d = Multiplication of two polynomials = Polynomial

`(a)/(b)* (c)/(d)` = Ratio of two polynomials

Therefore, product will be a rational expression.

Option (3) will be the correct option.
