Calculati:
a)0,15•1,2+6,25:2,5=
b)17,57-0,2•3+1,44:1,2=
c)3,5+10³•(0,3)³-79,8:4,2=
d)48:0,2+3,2²:1,6-4,3•0,1=

Answer 1

a)
0,15•1,2+6,25:2,5=
0,18+2,5=2,68

b)17,57-0,2•3+1,44:1,2=
17,57-0,6+1,2=16,97+1,2=18,17


c)3,5+10³•(0,3)³-79,8:4,2=
3,5+(10·0,3)³-79,8:4,2=
3,5+3³-19=3,5+27-19=11,5


d)48:0,2+3,2²:1,6-4,3•0,1=240+10,24:1,6-0,43=240+6,4-0,43=246,4-0,43=245,97
