How do you write a rational number as a decimal?
You divide the numerator of the rational expression by its denominator.
Is 2 divided by 0 a rational number?
Undefined: You cannot divide by zero
Is 6 divided by 0 a rational number?
Undefined: You cannot divide by zero
8x to the zero power?
Anything raised to the power of zero is zero !
Is 17.02 a rational number?
Is 12.05 a rational number or irrational number?
When is rational expression undefine or meaningless?
A rational number is any number that can be expressed as a fraction. It becomes meaningless or undefined when the lower number, the denominator, its 0 (zero)
What makes a rational expression undefined?
a rational express ion undefined when the denominator is 0 because we cannot dvide by 0. For example, 9/x is undefine when x is 0 because we would be dividing by 0. Similarly 2/(7-x) is undefined for x=7 because we once again have a zero in the denominator. To find where a rational expression is undefined, set the denominator equal to 0 so if we have p/q where q is any number or expression, set and solve q=0 From, Doctor Huge Dick
Is a rational number is a rational expression?
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
Ratio of two integers?
Can be an integer, a rational number or undefined.
Is zero always or sometimes a rational number?
Zero by definition is always a rational number. It can sometimes be the cause of mathematical concepts being undefined. For example, a number can not be divided by zero. Dividing by zero is undefined.
Why 5 divided by 0 undefined?
Undefined: You cannot divide by zero
Is a rational number a rational expression?
Yes, but the converse is not true.
What is a rational algebraic expression?
A rational number is any number that can be written in the form a/b, where a and b are integers and b ≠0. it is necessary to exclude 0 because the fraction represents a ÷ b, and division by zero is undefined.A rational expression is an expression that can be written in the form P/Q where P and Q are polynomials and the value of Q is not zero.Some examples of rational expressions:-5/3; (x^2 + 1)/2; 7/(y -1); (ab)/c; [(a^2)(b]/c^2; (z^2 + 3z + 2)/ (z + 1) ect.Like a rational number, a rational expression represents a division, and so the denominator cannot be 0. A rational expression is undefined for any value of the variable that makes the denominator equal to 0. So we say that the domain for a rational expression is all real numbers except those that make the denominator equal to 0.Examples:1) x/2Since the denominator is 2, which is a constant, the expression is defined for all real number values of x.2) 2/xSince the denominator x is a variable, the expression is undefined when x = 03) 2/(x - 1)x - 1 ≠0x ≠1The domain is {x| x ≠1}. Or you can say:The expression is undefined when x = 1.4) 2/(x^2 + 1)Since the denominator never will equal to 0, the domain is all real number values of x.
