Question

Calcule:
a)58-5.(-3)³-(-2)².(+5)²
b)125+3.(-4)²-(-3)⁴:(-9)²
c)(-6)²-(+2)³:(-4)¹
d)(-68+82-23)²
e)L=(-4)²+32​

Answer 1

Resposta:

a) +43   b) +172    c) +38    d) +81    e) +48

Explicação passo-a-passo:

a)58-5.(-3)³-(-2)².(+5)²  => 8 - 5. (-27) - (+4).(+25)=> 8 +135 - 100 = +43

b)125+3.(-4)²-(-3)⁴:(-9)² => 125 + 3.(+16)- (+81):(+81)=>  125 + 48 - (+1)=>

125 + 48 - 1 => +172

c)(-6)²-(+2)³:(-4)¹ => (+36)-(+8):(-4)=> (+36) - (-2)=> +36 + 2 = + 38

d)(-68+82-23)² => (-9)² => +81

e)L=(-4)²+32​ => 16+32​ = +48
