Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Nomor 1
\large\text{$\begin{aligned}\frac{ab\sqrt{c}}{\sqrt{a}\sqrt{bc}}=\boxed{\,\bf\sqrt{ab}\,}\end{aligned}$}

Nomor 2
\large\text{$\begin{aligned}\frac{\sqrt{a}\sqrt[3]{bc}}{\sqrt[6]{{a}^2{b}^4{c}^3}}=\boxed{\,\sqrt[\bf6]{\bf\frac{a}{b^2c}}\,}\end{aligned}$}

(untuk kedua soal, jawabannya tidak ada pada opsi jawaban)

Pembahasan

Nomor 1

\large\text{$\begin{aligned}\frac{ab\sqrt{c}}{\sqrt{a}\sqrt{bc}}&=\frac{ab\sqrt{c}}{\sqrt{a}\sqrt{b}\sqrt{c}}\\&=\frac{a}{\sqrt{a}}\cdot\frac{b}{\sqrt{b}}\cdot\frac{\cancel{\sqrt{c}}}{\cancel{\sqrt{c}}}\\&=\frac{\cancel{\sqrt{a}}\sqrt{a}}{\cancel{\sqrt{a}}}\cdot\frac{\cancel{\sqrt{b}}\sqrt{b}}{\cancel{\sqrt{b}}}\\&=\sqrt{a}\sqrt{b}\\&=\boxed{\,\bf\sqrt{ab}\,}\end{aligned}$}
\blacksquare

Nomor 2

\large\text{$\begin{aligned}\frac{\sqrt{a}\sqrt[3]{bc}}{\sqrt[6]{{a}^2{b}^4{c}^3}}&=\frac{\sqrt[6]{a^3b^2c^2}}{\sqrt[6]{{a}^2{b}^4{c}^3}}\\&=\sqrt[6]{\frac{a^3b^2c^2}{{a}^2{b}^4{c}^3}}\\&=\sqrt[6]{a^{3-2}\,b^{2-4}\,c^{2-3}}\\&=\sqrt[6]{a\,b^{-2}\,c^{-1}}\\&=\boxed{\,\sqrt[\bf6]{\bf\frac{a}{b^2c}}\,}\\\end{aligned}$}
\blacksquare
