Szczegółowe wyjaśnienie:
Obliczamy:
[tex]\boxed{\sqrt{10} \approx 3,16}\\\\3\sqrt{10} -8 \approx 1,48~~\Rightarrow ~~\huge\boxed{3\sqrt{10} -8 > 0}\\\\3-\sqrt{10} \approx -0,16~~\Rightarrow~~\huge\boxed{3-\sqrt{10} < 0}\\\\12-4\sqrt{10} \approx -0,64~~\Rightarrow~~\huge\boxed{12-4\sqrt{10} < 0}[/tex]
[tex]\mid 3\sqrt{10} -8\mid +\mid 3-\sqrt{10} \mid -\mid 12-4\sqrt{10} \mid = 3\sqrt{10} -8-3+\sqrt{10} -(-12+4\sqrt{10} ) =3\sqrt{10} -8-3+\sqrt{10} +12-4\sqrt{10} =3\sqrt{10} +\sqrt{10} -4\sqrt{10} -8-3+12=-11+12=\huge\boxed{1}[/tex]
