Question

Calcule as expressões baixo:

A)$97+ \sqrt{1089} -(15+6)- \sqrt{1}$
B)$78-93+[16- \sqrt{4} (6-2)]}$
C)$63+28-[ \sqrt{100}+15-] 3$
D)$\sqrt{49}+[26-30+(63+9-2 ^{3})]$

Answer 1

a) 97+33-(21)-1=
97+33-21-1=
130 - 22 = 108
b)78-93+[16-\/4(6-2) =
-15+[16-8] =
-15+8 = -7
c)63+28-10+15-3=
106 - 13 = 93
d)7+[26 - 30 + (63+9-8)]=
7+[26-30+64]=
7+[60]= 7 + 60 = 67
Um abraço.
