Bentuk rasional dari ${\sf{\dfrac{3\sqrt{\sf5}-10}{\sqrt{\sf5}}={\boldsymbol{\textsf{\textbf{3}}-\textsf{\textbf{2}}\sqrt{\textsf{\textbf{5}}}}}}}$

Pembahasan

$\begin{aligned}{\sf{\frac{3\sqrt{\sf5}-10}{\sqrt{\sf5}}}}&={\sf{\frac{3 \sqrt{\sf5}-10}{\sqrt{\sf5}}\times\frac{\sqrt{\sf5}}{\sqrt{\sf5}}}}\\&={\sf{\frac{3\sqrt{\sf5}-10\left(\sqrt{\sf5}\right)}{\sqrt{\sf5}\sqrt{\sf5}}}}\\&={\sf{\frac{15-10\sqrt{\sf5}}{5}}}\\&={\sf{3-2\sqrt{\sf5}}}\end{aligned}$

Penjelasan dengan langkah-langkah:

= (3√5 - 10)/√5

= (3√5 - 10)/√5 . √5/√5

= √5(3√5 - 10)/(√5²)

=(3√25 - 10√5)/5

= (3(5) - 10√5)/5

= (3 - 2√5)
