Simply type into the app below and edit the expression. The simplest case we can have. How would we find the answer without that? In general, roots tend to be irrational, so the procedure is called rationalization in math language. In general, it may happen that the thing we get after rationalization in math can still be made simpler. For instance, we could easily agree that we would not leave an answer in the form of 3 + 4, but would write 7 instead. In other words, we again multiply by ᵏ√(yᵏ⁻¹) / ᵏ√(yᵏ⁻¹) and obtain x * y underneath as a result. sum / radical - (a * ⁿ√b + c * ᵐ√d) / (x * ᵏ√y) To rationalize a denominator, start by multiplying the numerator and denominator by the radical in the denominator. ... To rationalize the denominator of the fraction, we multiply the numerator and denominator by $\sqrt{2}$ $\frac{5}{\sqrt{2}}\frac{\sqrt{2}}{\sqrt{2}}$ 3. But what does rationalize mean? Then we use the fact that multiplying fractions translates to numerator times numerator over denominator times denominator. In our case, we need to tackle √3, so we write: ³√18 / (2 * √3) = [³√18 / (2 * √3)] * (√3 / √3) = (³√18 * √3) / (2 * √3 * √3) = ⁶√8748 / 6 = (3 * ⁶√12) / 6 = 0.5 * ⁶√12. Rewrite as .
