Answer 1

Resposta:

a)

3³×(12+56:8) -7²=

9 x (12+7) -49 =

9x 19 -49 =

171 - 49 =

= 122 ✔️

b)

20²-[7³-(89-4²)]=

400 - [343 - (89-16)] =

400 - [343 - 73]=

400 - 270 =

= 130✔️

c)

6²:(6+1-1) +12×3=

36 ÷ 6+ 36 =

6 +36 =

=42✔️

d)

(8²-4) :15+(3+10) ²=

(64-4)÷15+ (13)^2 =

60÷15 +169 =

4 +169 =

= 173 ✔️
