Question

¯/¯¯0,49 *225 - 1 целая 11/25 б)¯/¯¯27/¯/¯¯12

Answer 1

если понято правильно, то

$sqrt{0,49 *225}-sqrt{1 frac {11}{25}}= sqrt{0,49} sqrt{225}-sqrt{frac{36}{25}}= 0.7*15-frac{6}{5}=10.5-1.2=9.3$

 

$frac{sqrt{27}}{sqrt{12}}=sqrt{frac{27}{12}}=sqrt{frac{9}{4}}=frac {sqrt{9}}{sqrt{4}}=frac {3}{2}$
