( pi ) x ( 3/pi ) = 3
The product of two rational numbers is always a rational number.
(pi) x (1/pi) = 1
sqrt(2) + sqrt(3) is irrational.
Not necessarily. The sum of two irrational numbers can be rational or irrational.
It can be, but need not be. [sqrt(5)+sqrt(2)] and [sqrt(5)-sqrt(2)] are both irrational. Their product is 5-2 = 3. The two numbers are conjugates of one another and the property that their product is an integer is used to rationalise denominator of surds.
sqrt(2)*sqrt(3) is an irrational product.
You get a product which can be rational or irrational.
The question is nonsense because the product of two rational numbers is never irrational.
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.
Because that is the definition of irrational numbers: They are the numbers that cannot be written as a ratio of two integers! A fraction is a ratio of two integers.
The product of two rational numbers is always a rational number.
Make the two irrational numbers reciprocals of each other. Ex.) 1/pi x pi = 1
(pi) x (1/pi) = 1
sqrt(2) + sqrt(3) is irrational.
No. The easiest counter-example to show that the product of two irrational numbers can be a rational number is that the product of √2 and √2 is 2. Likewise, the cube root of 2 is also an irrational number, but the product of 3√2, 3√2 and 3√2 is 2.
No. The square root of two is an irrational number. If you multiply the square root of two by the square root of two, you get two which is a rational number.
Not necessarily. The sum of two irrational numbers can be rational or irrational.
