Va rog e urtgent va rog!

Answer 1

a)(9.7-3.2)÷0.5+0.1²=
(6.5)÷0.5+0.01=13+0.01=13.01
b)3.2+2.1×(7.5-2.5×2)=
3.2+2.1×(7.5-5)=
3.2+2.1×2.5=
3.2+5.25=8.45

c)35-2×(4.9÷0.7+2÷.02)=
35-2×(7-10)=
35-2×(-3)=
35+6=41
d)3.21×1.3-4.17×(1.5÷5+0.7)=
3.21×1.3-4.17×(0.3+0.7)=
3.21×1.3-4.17×1=
4.173-4.17=0.003

e)(4.4×2.5+0.1)÷3-3.7=
(11+0.1)÷3-3.7=
11.1÷3.-3.7=3.7-3.7=0

f)3.25+5×(7.25÷5-1)=
3.25+5×(1.45-1)=
3.25+5×0.45=
3.25+2.25=5.5
