... = V(3*16) - 13*V12 / V25 + V(108/25) = V3 * V16 - 13*V(3*4) / 5 + V108 / 5 =
4V3 - 26V3 / 5 + V(3*9*4) / 5 = (20V3 - 26V3 + 6V3) / 5 = 0

$\sqrt{48} -13 \sqrt{12/25}+ \sqrt{4 \frac{8}{25} } =$
$= \sqrt{16*3} -13/5 \sqrt{4*3}+ \sqrt{\frac{9*12}{25} }=$
$= 4\sqrt{3} -5,2 \sqrt{3}+ 1,2\sqrt{{3} }= \sqrt{3}(4-5,2+1,2)= \sqrt{3}*0=0$
