    Đáp án:

    $⇒x=±\dfrac{12}{5}$

    $\text{Tâm Langửi bạn}$

    Giải thích các bước giải:

     $\dfrac{x^2}{6}=\dfrac{24}{25}$

    $⇔x^2×25=6×24$

    $⇒x^2×25=144$

    $⇒x^2=\dfrac{144}{25}$

    $⇒x^2=(\dfrac{12}{5})^2$

    $⇒x=±\dfrac{12}{5}$

    $\dfrac{x^2}{6}=\dfrac{24}{25}$

    $⇔25.x^2=6.24$

    $⇔25.x^2=144$

    $⇔x^2=\dfrac{144}{25}$

    $⇔x^2=\left (\dfrac{12}{5} \right )^2$

    $⇔\left[ \begin{array}{1}x=\dfrac{12}{5}\\x=\dfrac{-12}{5}\end{array} \right.$
