Answer 1

a) 210:[16+3.(6+3.2^2)]-3

=210:[16+3.(6+3.4)]-3

=210:[16+3.(6+12)]-3

=210:[16+3.18]-3

=210:[16+54]-3

=210:70-3

=3-3

=0

Answer 2

\(500-\left\{5.\left[409.\left(2^3.3-21\right)^2\right]\right\}-3\)

Answer 3

500-{5.[409.(8.3-21)^2]}-3

500-{5.[409.(24-21)^2]}-3

500-{5.[409.3^2]}-3

500-{5.[409.9]}-3

500-{5.3681}-3

500-18405-3
