Answer 1

Răspuns:

1)

=0,09+12,5-0,66=11,93

2)

=1,1⁶÷1,1⁴+3×(²15/6+³15/4)×1,5=

=1,1²+3×(30/12+45/12)×1,5=

=1,21+3×75/12×1,5=

=1,21+75/4×1,5=

=1,21+18,75×1,5=

=1,21+28,125=29,335

3)

=3+{0,4+[25/2×(0,09+3)-2,4]×10}=

=3+[0,4+(12,5×3,09-2,4)×10]=

=3+[0,4+(38,625-2,4)×10]=

=3+[0,4+36,225×10]=

=3+(0,4+362,25)=

=3+362,65=

=365,65
