Question

\(x^2\cdot\sqrt{7}=\dfrac{\sqrt{6363}}{\sqrt{707}}\)

Answer 1

\(x^2.7=\dfrac{\sqrt{6363}}{\sqrt{707}}\)

<=> \(7x^2=\dfrac{3\sqrt{707}}{\sqrt{707}}\)

<=> \(7x^2=3\)

<=> \(x^2=\dfrac{3}{7}\)

<=> x = \(-\sqrt{\dfrac{3}{7}}\) hoặc x = \(\sqrt{\dfrac{3}{7}}\)

Answer 2

=> \(^{x^2}\). \(\sqrt{7}\) = \(\dfrac{3\sqrt{707}}{\sqrt{707}}\)

=> \(^{x^2}\) . \(\sqrt{7}\) = 3

=> \(^{x^2}\) = \(\dfrac{3}{\sqrt{7}}\)

=> \(^{x^2}\) = \(\dfrac{3\sqrt{7}}{7}\)

=> \(^x\) = 1,065

Sai đừng trách mình nhé
