Question

Me ajudem na resolução da questão 04?

Answer 1

Olá,

(1/2)³ = 1³/2³ = 1/8 
(1/4)² = 1²/4² = 1/16
2⁻³ = 1/2³ = 1/8 
16⁰ = 1

(1/2)³+(1/4)²-2⁻³+16⁰ = 1/8 + 1/16 - 1/8 + 1 = 1/8 - 1/8 + 1/16 + 1
(1/2)³+(1/4)²-2⁻³+16⁰ = 0 + 1/16 + 1 = 1/16 + 1 = (1+16)/16 = 17/16

Resposta:

B) 17/16

Answer 2

(1/2)^3+(1/4)²-2^-3 +16^0=

(1/8)+(1/16)-(1/2)^3+1=           

(1/8)+(1/16)-(1/8)+1=  

 (2+ 1-2+16)/16= 17/16  

resp: alternativa (b)
