Answer 1

№844
1) = 0,4*25-1/4*12=10-3=7
2) = 8*0,5+5= 4+5=9
3) = 3*0,5-25=1,5-25=-23,5
4) = √36/25+√81/25-0,04√10000= 6/5+9/5-4=15/5-4=-1
5) = 1/5*25-3/17*17=5-3=2
№845
1) =3-1,3= 1,7
2) = 9*15 -225*3=135-675=-540
3) = 50*7/25-1/4*18=14-4,5=9,5
4) =33-6=27
5) = 4/9*6,3-5/49*7,7+1/25*75=2,8-5/7*1,1+3=5,8-11/14=5,21
6) =1/2*8+22-0,3*30=4+22-9=17
