$\frac{5}{\sqrt{7}}\cdot \frac{\sqrt{7}}{\sqrt{7}}$
Learn how to solve rationalisation problems step by step online. Rationalize and simplify the expression 5/(7^(1/2)). Apply the formula: \frac{a}{b}=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}, where a=5 and b=\sqrt{7}. Apply the formula: \frac{a}{b}\frac{c}{f}=\frac{ac}{bf}, where a=5, b=\sqrt{7}, c=\sqrt{7}, a/b=\frac{5}{\sqrt{7}}, f=\sqrt{7}, c/f=\frac{\sqrt{7}}{\sqrt{7}} and a/bc/f=\frac{5}{\sqrt{7}}\cdot \frac{\sqrt{7}}{\sqrt{7}}. Apply the formula: x\cdot x=x^2, where x=\sqrt{7}. Apply the formula: \left(x^a\right)^b=x, where a=\frac{1}{2}, b=2, x^a^b=\left(\sqrt{7}\right)^2, x=7 and x^a=\sqrt{7}.
