what is the excluded value of the rational expression?
450450
Excluded values are simply that: values that are excluded, or left out. These are values that will make the denominator of a rational expression equal to 0. Remember, you're not allowed to divide by 0, so these values are important to identify and exclude while solving.

No. The number represented by is a rational number (in precise terms, it is the unique rational number which, when multiplied by seven, gives twenty two), which has (by dint of its rationality) a repeating decimal representation.

An algebraic expression is a combination of integer constants, variables, exponents and algebraic operations such as addition, subtraction, multiplication and division. 5x, x + y, x-3 and more are examples of algebraic expression.

No, the difference of two positive rational numbers is not always positive.

Another rule of thumb is if there are any variables in the denominator of a fraction then the algebraic expression isn't a polynomial. There are lots of radicals and fractions in this algebraic expression, but the denominators of the fractions are only numbers and the radicands of each radical are only a numbers.

Another useful way of thinking about polynomial and rational expressions is that polynomial expressions are those algebraic expressions that can be evaluated using a finite number of additions and multiplications (and subtractions), whereas rational expressions may also require division for their evaluation.

A rational expression is undefined when the denominator is equal to zero. To find the values that make a rational expression undefined, set the denominator equal to zero and solve the resulting equation. Example: 0 7 2 3 x x − Is undefined because the zero is in the denominator.

Indeed it is. The Roman numeral I represents the number 1, which is rational as it can be expressed as a ratio of two integers, one example of which is 1/1. ... Rational numbers are a subclass of real numbers. Therefore, i cannot be rational.

From Wikipedia, the free encyclopedia. In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).

A sum, difference, product, or quotient of two rational expressions is a rational expression. Quoth the Shmaven, "As long as we don't try to divide by 0, bro." Rational expressions are incredibly similar to rational numbers (fractions). For one, they both have one of those line thingies in the middle.

(i) 23 is not a perfect square values so that, it is an irrational number. The decimal expansion of above number is terminating, so that it is a rational number. The decimal expansion of above number is non-terminating recurring, so that, it is a rational number.

Any algebraic expression, that is a quotient of two other algebraic expressions, is called a rational algebraic expression. ... We say that a rational algebraic expression is meaningless for those values of the variable for which the denominator Q is zero.

A short proof of the irrationality of √2 can be obtained from the rational root theorem, that is, if p(x) is a monic polynomial with integer coefficients, then any rational root of p(x) is necessarily an integer. Applying this to the polynomial p(x) = x2 − 2, it follows that √2 is either an integer or irrational.

The number √−1 is not real. Since the rationals are just a particular type of real number, it cannot be rational, either. and so a2=−b2. Since b2 is certainly positive, that means a2 is certainly negative, which is impossible.

A rational expression is proper if the degree of the numerator is less than the degree of the denominator, and improper otherwise. ... In the third example, the numerator and denominator are both fourth-degree polynomials, so the rational function is improper.
