Formula Used in “Rationalize Denominator Calculator”
The primary goal of the “Rationalize Denominator Calculator” is to eliminate any irrational numbers present in the denominator of a fraction. This is generally done by multiplying both the numerator and denominator by an appropriate expression that transforms the denominator into a rational number. The standard formula for rationalizing the denominator can be represented as follows:
Formula:
If the original fraction is ( frac{a}{bsqrt{c}} ), then the rationalized form is ( frac{a cdot sqrt{c}}{b cdot c} ).
Step-by-Step Breakdown of the Formula
To facilitate a better understanding, let’s break down each component of the formula:
- a: This represents the numerator of the original fraction.
- b: This denotes the coefficient of the irrational square root in the denominator.
- c: This is the radicand (the number under the square root) that is irrational.
- ( sqrt{c} ): This term indicates the square root of the radicand.
Calculation Process
To rationalize a denominator, follow these steps:
- Identify the irrational component in the denominator.
- Determine the appropriate conjugate or expression needed to eliminate the square root.
- Multiply both the numerator and denominator by that expression.
- Simplify the resulting expression if needed.
Example Calculation
Consider a fraction that needs to be rationalized:
Original Fraction: ( frac{3}{2sqrt{5}} )
| Step | Action | Result |
|---|---|---|
| 1 | Identify & Multiply | Multiply numerator and denominator by ( sqrt{5} ) |
| 2 | Calculate Numerator | ( 3 cdot sqrt{5} = 3sqrt{5} ) |
| 3 | Calculate Denominator | ( 2sqrt{5} cdot sqrt{5} = 2 cdot 5 = 10 ) |
| 4 | Final Result | ( frac{3sqrt{5}}{10} ) |
Thus, the original fraction ( frac{3}{2sqrt{5}} ) has been successfully transformed into its rationalized form: ( frac{3sqrt{5}}{10} ).
