Question

Which statement about his product must be true

Answer 1

Answer:

Option (3)

Step-by-step explanation:

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

$\frac{a}{b}\times \frac{c}{d}$ = $\frac{a.c}{b.d}$

a.c = Multiplication of two polynomials = Polynomial

b.d = Multiplication of two polynomials = Polynomial

$\frac{a}{b}\times \frac{c}{d}$ = Ratio of two polynomials

Therefore, product will be a rational expression.

Option (3) will be the correct option.
