No.Suppose a and b are two rational numbers.
Then they can be written as follows: a = p/q, b = r/s where p, q, r and s are integers and q, s >0.
Then a*b = (p*r)/(q*s).
Using the properties of integers, p*r and q*s are integers and q*s is non-zero. So a*b can be expressed as a ratio of two integers and so the product is rational.

What product is true about the irrational and rational numbers?
The product of 2 rationals must be rational. The product of a rational and an irrational is irrational (unless the rational is 0) The product of two irrationals can be either rational or irrational.
What happens when two irrational numbers are multiplied?
You get a product which can be rational or irrational.
Is 10x 3.14 irrational?
The product of two rational numbers, as in this example, is always RATIONAL.However, if you mean 10 x pi, pi is irrational; the product of a rational and an irrational number is ALWAYS IRRATIONAL, except for the special case in which the rational number is zero.
Are there more rational numbers than irrational numbers true or false?
In between any two rational numbers there is an irrational number. In between any two irrational numbers there is a rational number.
Sum of two irrational numbers?
Can be rational or irrational.
