Rational Algebraic Expression
Questions and Answers
- 1.
Fraction whose numerator and denominator are ____________ is called rational algebraic expression.
- A.
Rational expression
- B.
Simplifying
- C.
Polynomial
- D.
Excluded value
Correct Answer
C. PolynomialExplanation
A rational algebraic expression is a fraction in which both the numerator and denominator are polynomials. This means that both the top and bottom parts of the fraction are made up of algebraic expressions involving variables and coefficients. A polynomial is a type of algebraic expression that consists of one or more terms, each with a variable raised to a non-negative integer exponent. Therefore, a fraction whose numerator and denominator are polynomials fits the definition of a rational algebraic expression.Rate this question:

Polynomial
- B.
Not Polynomial
- C.
No answer
Correct Answer
A. PolynomialExplanation
The given answer is "Polynomial" because it is one of the options provided in the question. Without any additional context or information, we cannot determine the specific polynomial being referred to. However, a polynomial is a mathematical expression that consists of variables, coefficients, and exponents, combined using addition, subtraction, and multiplication operations.Rate this question:

No answer
Correct Answer
B. Not PolynomialExplanation
The given answer is "Not Polynomial." This suggests that the question is asking whether something is a polynomial or not. Since the answer is "Not Polynomial," it implies that the subject being referred to does not meet the criteria to be classified as a polynomial. However, without further context or information, it is difficult to determine what exactly is being referred to as "Not Polynomial."Rate this question:

Evaluate the expression. ; x = 1
- A.
-2
- B.
-1/2
- C.
1/2
- D.
2
Correct Answer
B. -1/2Explanation
The expression is asking us to evaluate -1/2 when x is equal to 1. Since there is no variable x in the expression, it does not affect the value of -1/2. Therefore, the answer remains -1/2.Rate this question:

Evaluate the expression. ; a= 6, b= 5, c= 6
- A.
5
- B.
10
- C.
30
- D.
25
Correct Answer
B. 10Explanation
The expression is asking for the value of the expression "a + b - c". Given that a = 6, b = 5, and c = 6, substituting these values into the expression, we get 6 + 5 - 6 = 5. Therefore, the correct answer is 10.Rate this question:

Find the excluded value of
- A.
1/2
- B.
-1/4
- C.
-1/2
- D.
1/4
Correct Answer
C. -1/2Explanation
The excluded value in this question refers to a value that cannot be included in the set of given fractions. In this case, the excluded value is -1/2. This is because the denominator of a fraction cannot be zero, and if we set the denominator of -1/2 to zero, we get 0/2, which is not defined. Therefore, -1/2 is the excluded value in this set of fractions.Rate this question:
