$\frac{4}{\sqrt{5}}\cdot \frac{\sqrt{5}}{\sqrt{5}}$
Learn how to solve razionalizzazione problems step by step online. Rationalize and simplify the expression 4/(5^(1/2)). Apply the formula: \frac{a}{b}=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}, where a=4 and b=\sqrt{5}. Apply the formula: \frac{a}{b}\frac{c}{f}=\frac{ac}{bf}, where a=4, b=\sqrt{5}, c=\sqrt{5}, a/b=\frac{4}{\sqrt{5}}, f=\sqrt{5}, c/f=\frac{\sqrt{5}}{\sqrt{5}} and a/bc/f=\frac{4}{\sqrt{5}}\cdot \frac{\sqrt{5}}{\sqrt{5}}. Apply the formula: x\cdot x=x^2, where x=\sqrt{5}. Apply the formula: \left(x^a\right)^b=x, where a=\frac{1}{2}, b=2, x^a^b=\left(\sqrt{5}\right)^2, x=5 and x^a=\sqrt{5}.
