Question

is 7 a rational number is 3 to the square root a rational number and is the product of 7+ 3 to the square root rational

Answer 1

7 = 7/1, which is a rational number.

sqrt(3) is not a rational number, since the root (which is approx. 1.732) cannot be expressed as the ratio of two integers.

Don't understand what you mean by "product of 7+ 3 to the sqrt." Please clarify this.
