3. 128
4. -243
5. 64
Explicación paso a paso:
1. Efectuar
-5-[-15+(14-6)]+(-12-8)-{-1+(8-2)+(7-8)}
-5-[-15+8]+(-20)-{-1+(6)+(-1)}
-5-[-7]+(-20)-{-1+ 6- 1}
-5-7-20-6
-38
-13-{-4+[6+(-5-5+10)+(-3)]-3}
-13-{-4+[6+0-3]-3}
-13-{-4+3-3}
-13-{4}
-13+4
-9
-10+{-1-[8-2+(5-1)]+12-[3-(6-9)]}
-10+{-1-[8-2+4]+12-[3-(-3)]}
-10+{-1-10+12-[3+3]}
-10+{-1-10+12-6}
-10-5
-15
2. Completa
-5x = -5 | x
-2xy = -2 | xy
x^5y^2z = 1 | x^5y^2z
3x^2wa = 3 | x^2wa
3.
2^5 * 2^2 = 5+2=7 2^7 = 128
4.
(-3)^2 * (-3)^3 = 2+3=5 -3^5 = -243
5.
(4)^4 / (4) = 4-1=3 (4)^3 = 64
