(a+b)^3=a^3+3a^2b+3ab^2+b^3 wzór na sześcian sumy
(\sqrt{3x}+\sqrt2)^3=
=(\sqrt{3x})^3+3(\sqrt{3x})^2*\sqrt2+3\sqrt{3x}*(\sqrt2)^2+(\sqrt2)^3=
=(\sqrt{3x})^2*\sqrt{3x}+3*3x*\sqrt2+3\sqrt{3x}*2+(\sqrt2)^2*\sqrt2=
=3x*\sqrt{3x}+9\sqrt2x+6\sqrt{3x}+2\sqrt2=
=3\sqrt3x*x^{\frac{1}{2}}+9\sqrt2x+6\sqrt{3x}+2\sqrt2=
=3\sqrt3x^{\frac{3}{2}}+9\sqrt2x+6\sqrt{3x}+2\sqrt2
