Question

помогите решить примеры
25х^2=4
6х^2=3
0.6^х2=4.8
1.5х^2=0.96

Answer 1

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