f) 2⁵-(16:2+3²)=
g) [100-(5²-3²)]:2=
h) 7+[5²:(10-5)+2³×2]=
i) 50-2×[8+(10-3²)-3]=
j) 2×[(6+7×√9):3²+(21-5×√4)]=​

Answer 1

Explicação passo-a-passo:

f) 32 - ( 8 + 9)=

32 - 17=

15

g) [ 100 - (25 - 9) ] :2=

[ 100 - 16] : 2=

84 : 2=

42

h) 7 + [ 25 : 5 + 8 × 2]=

7 + [ 5 + 16]=

7 + 21=

28

i) 50 - 2× [ 8+(10-9) -3]=

50 - 2× [ 8+1-3]=

50 - 2× [9-3]=

50 - 2× 6=

50 - 12=

38

j) 2× [( 6 + 7×3): 9 + (21 - 5×2)]=

2× [ (6+21) : 9 + (21 - 10)]=

2× [ 27 : 9 + 11]=

2× [ 3 + 11]=

2× 14=
