The same rule works for quotient of two irrational numbers as well.Here, the symbol derives from the German word Quotient, which can be translated as "ratio," and first appeared in Bourbaki's Algèbre (reprinted as Bourbaki …To solve a rational expression start by simplifying the expression by finding a common factor in the numerator and denominator and canceling it out. Then, check for extraneous solutions, which are values of the variable that makes the denominator equal to zero. These solutions must be excluded because they are not valid solutions to the equation.

The word real distinguishes them from the imaginary numbers, involving the symbol i, or Square root of √ −1. Complex numbers such as 1 + i have both a real (1) and an imaginary (i) part.

With ( − 4) 2 , we took the opposite of 4 first, because the negative sign was inside the grouping symbols. − 4 2 = − ( 4 ⋅ 4) Evaluate the power. = − 16 Take the opposite. With − 4 2 , we squared 4 first, because exponents come ...Irrational Numbers Symbol. Generally, we use the symbol “P” to represent an irrational number, since the set of real numbers is denoted by R and the set of rational numbers is denoted by Q. We can also represent irrational numbers using the set difference of the real minus rationals, in a way $\text{R} – \text{Q}$ or $\frac{R}{Q}$.

Since any integer can be written as the ratio of two integers, all integers are rational numbers.becomes "There is a smallest rational number." We can prove this by saying: Let r be any rational number. Since r is a rational number we know that r/2 is also rational. Because r/2 is rational, we can assume r/2 < r, therefore there is no smallest rational number.
