The product of two rational numbers is irrational.
PtichkaEL [24]

Answer:

The statement is false.

Step-by-step explanation:

Here we need to remember some things:

Integer numbers are closed under multiplication.

This means that for two integers a and b, the product a*b is also an integer.

A rational number is a number that can be written as the quotient of two integer numbers.

An irrational number is a number that can't be written as the quotient of two rational numbers.

Now let's see the statement:

"The product of two rational numbers is irrational."

The product of two rational numbers is written as:

\frac{a}{b} *\frac{c}{d}

Where a, c, b, and d are integers.

We can rewrite that product as:

\frac{a*c}{b*d}

Because of the first property, we know that a*c is an integer, and b*d is also an integer, so here we have a quotient of two integer numbers, so this is a rational number.

Then the product of two rational numbers is a rational number.

Then the statement is false.

HELP PLZ ASAP HELP
Basile [38]

Answer:

4.5 Cubic Feet

Step-by-step explanation:

1. You want to find the volume of the box. (Length x width x height)

2.5 x 2 x 1.5 = 7.5

2. The present has a volume of 3 cubic feet, so you would subtract that from the volume of the box.

7.5 - 3 = 4.5

3. The volume of the empty space in the box is 4.5 cubic feet.

Hope this helped! :)
