Răspuns:

a)(2⁴•3la8-3la8):5-27³=

=(16•6561-6561):5-27³=

=(104976-6561):5-27³=

=98415:5-27³=

=98415:5-19683=

=19683-19683=

=0

b)[(17²-11•3):8²+3•16]:13=

=[(289-11•3):64+3•16]:13=

=[(289-33):64+3•16]:13=

=(256:64+3•16):13=

=(4+3•16):13=

=(4+48):13=

=52:13=

=4

c)[12•15-(2⁴•5⁴-98²):2²:3²]:13

=[12•15-(16•625-9604):4:9]:13

=[12•15-(10000-9604):4:9]:13=

=(12•15-396:4:9):13=

=(180-396:4:9):13=

=(180-99:9):13=
