Does the multiplication property work when the radicands are rational expressions?
true
Are rational numbers closed under division multiplication addition or subtraction?
Rational numbers are closed under addition, subtraction, multiplication. They are not closed under division, since you can't divide by zero. However, rational numbers excluding the zero are closed under division.
What is multiplicative inverse in rational numbers?
The inverse function of multiplication is division.
How do multiplication and division of rational number relate to one another?
it is a replica of the same thing but backwards like 7x3=21 but in division it is 21 divided by 7=3 or 21 divided by 3 = 7
When can cross multiply be used as a shortcut to the solution while solving rational expressions?
in division

Division by a factor that can be zero.
Are rational numbers are closed under addition subtraction multiplication and division?
They are closed under all except that division by zero is not defined.
How do you use reciprocals to solve a division problem with rational numbers?
Division by any non-zero number is the same as multiplication by its reciprocal.
How would you describe rational algebraic expressions?
A collection of more than one term.
Is 8 over 9 an irrational number?
Any addition, subtraction, multiplication, or division of rational numbers gives you a rational result. You can consider 8 over 9 as the division of 8 by 9, so the result is rational.
