$\frac{7}{\sqrt{7}}\cdot \frac{\sqrt{7}}{\sqrt{7}}$
Learn how to solve razionalizzazione problems step by step online. Rationalize and simplify the expression 7/(7^(1/2)). Apply the formula: \frac{a}{b}=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}, where a=7 and b=\sqrt{7}. Apply the formula: \frac{a}{b}\frac{c}{f}=\frac{ac}{bf}, where a=7, b=\sqrt{7}, c=\sqrt{7}, a/b=\frac{7}{\sqrt{7}}, f=\sqrt{7}, c/f=\frac{\sqrt{7}}{\sqrt{7}} and a/bc/f=\frac{7}{\sqrt{7}}\cdot \frac{\sqrt{7}}{\sqrt{7}}. Apply the formula: x\cdot x=x^2, where x=\sqrt{7}. Apply the formula: \frac{a}{a}=1, where a=7 and a/a=\frac{7\sqrt{7}}{7}.
