Answer 1

Explicação passo-a-passo:

$100-\{[30-(5+1)^2]:6+9\}:8=\\ \\ 100-\{[30-(6)^2]:6+9\}:8=\\ \\ 100-\{[30-(36)]:6+9\}:8=\\ \\100-\{[-6]:6+9\}:8=\\ \\ 100-\{-1+9\}:8=\\ \\ 100-\{+8\}:8=\\ \\ 100-(+1)=\\ \\ 100-1=99$

-----------------------------------------------

$-2+\{-5-[-2-(-2)^3-3-(3-2)^9]+5\}=\\ \\ -2+\{-5-[-2-(-8)-3-(1)^9]+5\}=\\ \\ -2+\{-5-[-2+8-3-1]+5\}=\\ \\ -2+\{-5-[+8-6]+5\}=\\ \\ -2+\{-5-(+2)+5\}=\\ \\ -2+\{-5-2+5\}=\\ \\ -2+\{-7+5\}=\\ \\ -2+(-2)=\\ \\ -2-2=-4$

---------------------------------------------------

$.[(7-2\times14):(-21)-(5-2)]:2=\\ \\ .[(7-28):(-21)-(+3)]:2=\\ \\.[ (-21):(-21)-3]:2=\\ \\ .{[+1-3]:2=$

$(-2):2=-1$
