Answer 1

O sa-ti scriu direct rezolvarea.
a) 0,25·1,6=
=0,4

b) (17,2+1,6):4=
=18,8:4
=4,7

c) 16,5+0,3·10=
=16,5+3
=19,5

d) 2,8+3,18·0,01=
=2,8+0,0318
=2,8318

e) 136,8-0,12:0,01=
=136,8-12
=124,8

f) 0,0009:0,0004+3,3027=
=2,25+3,3027
=5,5527

g) 21,889+24,01:0,7=
=21,889+34,3
=56,189

h) 0,64+(2,2:0,5):1,1=
=0,64+4,4:1,1
=0,64+4
=4,64

i) [0,7+(5,8-1,1)]:0,6=
=(0,7+4,7):0,6
=5,4:0,6
=9

j) [11,3-(7-0,95)]:4,2-1,5=
=(11,3-6,05):4,2-1,5
=5,25:4,2-1,5
=1,25-1,5
=-0,25

k) $[(12,375-10,37)^{3}$:2,56·100]:25=
=$(2,005^{3}$:2,56·100):25
=(8,06015012:2,56·100):25
=(3,14849614·100):25
=314,849614:25
=12,5939846

l) {(1,21+4,84+10,89+19,36+30,25):5,5}:1,21=
=(66,55:5,5):1,21
=12,1:1,21
=10

m) $[25+(7,5-7,3)-25,2] ^{2}$:0,008=
=$(25+0,2-25,2)^{2}$:0,008
=$0^{2}$:0,008
=0:0,008
=0
