Giải thích các bước giải:
$\dfrac{x^2}{6}=\dfrac{24}{25}$
$⇔x^2×25=6×24$
$⇒x^2×25=144$
$⇒x^2=\dfrac{144}{25}$
$⇒x^2=(\dfrac{12}{5})^2$
$⇒x=±\dfrac{12}{5}$
Xin câu trả lời hay nhất
$\dfrac{x^2}{6}=\dfrac{24}{25}$
$⇔25.x^2=6.24$
$⇔25.x^2=144$
$⇔x^2=\dfrac{144}{25}$
$⇔x^2=\left (\dfrac{12}{5} \right )^2$
$⇔\left[ \begin{array}{1}x=\dfrac{12}{5}\\x=\dfrac{-12}{5}\end{array} \right.$
