Question

Calcule as expressões.
a ) 29 - 100 : 5² + 3 · √16
b ) ( 17 + 7²) + ( 42 : √36 )
c ) [ 28-3^4 : 9 + ( 32 : 2 - 6 ) ] - 18

Answer 1

a) 29-100:25+3.4=
29-4+12=
41-4= 37

b)(17+49)+(42:6)=
(17+49)+(7)=
66+7= 73

c)[28-243:9+(16-2)]-8=
[28-27+(14)]-8=
[28-27+14]-8=
[15]-8=
15-8= 7
Um abraço.
