Question

alguem sabe essa expressão ?

Answer 1

.
$30-8^2\div(-2)^5+(-54)\div(-1-2)^3-10^2= \\ \\ 30-64\div(-32)+(-54)\div(-3)^3-100= \\ \\ 30+2+(-54)\div(-27)-100= \\ \\ 30+2+(+2)-100= \\ \\ 30+2+2-100= \\ 34-100= \\ \\ -66$

Answer 2

30 - 8² : (- 2$)^{5}$ + ( - 54) : ( - 1 - 2 )³ - 10² =
30 - 64 : (- 32) - 54 : (- 3 )³ - 100 =
30 + 2 - 54 : - 27 - 100 =
32  + 2 - 100 =
34 - 100 =
- 66
