Помогите решить примеры25х^2=46х^2=30.6^х2=4.81.5х^2=0.96

Решите задачу:

$25x^2=4 \\ x^2= \frac{4}{25} \\ x_1= \sqrt{ \frac{4}{25}}= \frac{2}{5}=0.4,x_2= -\sqrt{ \frac{4}{25}}=- \frac{2}{5}=-0.4 \\ 6x^2=3 \\ x^2= \frac{3}{6}= \frac{1}{2} \\ x_1= \sqrt{ \frac{1}{2}}=\frac{1}{ \sqrt{2}},x_2=-\sqrt{ \frac{1}{2}}=-\frac{1}{ \sqrt{2}} \\ 0.6x^2=4.8 \\ x^2= \frac{4.8}{0.6}=8\\ x_1= \sqrt{8}}=2\sqrt{2},x_2=-\sqrt{8}=-2\sqrt{2} \\ 1.5x^2=0.96 \\ x^2= \frac{0.96}{1.5}=0.64 \\ x_1= \sqrt{0.64}=0.8,x_2=-\sqrt{0.64}=-0.8$
