What else can I help you with?
If the equation of a rational function is a rational expression is the function rational?
Yes. Rational functions must contain rational expressions in order to be rational.
Are rational numbers closed under multiplication?
Rational numbers are closed under multiplication, because if you multiply any rational number you will get a pattern. Rational numbers also have a pattern or terminatge, which is good to keep in mind.
Is there a difference between rational expressions and rational equations?
Yes. An equation has an "=" sign.
After multiplying or dividing two rational expressions it is sometimes possible to the resulting expression?
After multiplying or dividing two rational expressions it is sometimes possible to simplify the resulting expression.
Difference between rational numbers and rational expressions?
A Rational number is a fraction of two integers; a rational expression is a fraction that contains at least one variable
Does the multiplication property work when the radicands are rational expressions?
true
If the equation of a function is a rational expressions the function is rational?
Yes. Rational functions must contain rational expressions in order to be rational.
Describe how multiplication and division of rational expressions can be done?
Suppose X1 = N1/D1 and X2 = N2/D2 are two rational expressions, where the numerators N1 and N2 and denominators D1 and D2 are simpler expressions. Then X1 * X2 = (N1*N2)/(D1*D2) and X1 / X2 = (N1*D2)/(D1*N2).
Does the Commutative Property apply to addition of fractions?
Yes, it applies to even multiplication of fractions and rational and irrational numbers.
Equations that contain rational expressions?
a rational function.
What is subtraction of rational expressions?
another rational expression.
How do you write mixed expressions as rational expressions?
8+3/n
How do multiplication and division of rational number relate to one another?
Division by a non-zero rational number is equivalent to multiplication by its reciprocal.
If the equation of a rational function is a rational expression is the function rational?
Yes. Rational functions must contain rational expressions in order to be rational.
Is a rational number closed for addition and for multiplication?
A rational number is not. But the set of ALL rational numbers is.
If the equation of a function is a rational expression the function is rational.?
Yes. Rational functions must contain rational expressions in order to be rational.
If the equation of a function is a rational expression is the function rational?
Yes. Rational functions must contain rational expressions in order to be rational.
