Question

Ti,f x biết: x^2/6=24/25

Answer 1

\(\frac{x^2}{6}=\frac{24}{25}\)

=> x².25 = 6 . 24

=> x² . 25 = 144

=> x² = 144 : 25

=> x² = 5,76 = 2,4² = (-2,4)²

=> x \(\in\){2,4 ; -2,4}

Answer 2

\(\frac{x^2}{6}=\frac{24}{25}\Rightarrow25x^2=24.6\Rightarrow25x^2=144\Rightarrow x^2=\frac{144}{25}=\left(\frac{12}{5}\right)^2=\left(-\frac{12}{5}\right)^2\)

=> x = 12/5 hoặc x = -12/5

Answer 3

\(\frac{x^2}{6}=\frac{24}{25}\)

\(\Rightarrow x^2.25=24.6\)

\(\Rightarrow x^2.25=144\)

\(\Rightarrow x^2=5,76\)

\(\Rightarrow x=2,4\)
