Question

(2^2×2^-3)^4/2×2^-8 - (1/7)^-1​

Answer 1

Resposta:

-57343/8192

Explicação passo-a-passo:

( 2^2 × 2^-3 )^4/2 × 2^-8 - ( 1/7 )^-1​

= ( 4 × 2^-3 )^4/2 × 2^-8 - ( 1/7 )^-1​

= ( 4 × 1/8 )^4/2 × 2^-8 - ( 1/7 )^-1​

= ( 1/2 )^4/2 × 2^-8 - ( 1/7 )^-1​

= 1/32 × 2^-8 - ( 1/7 )^-1​

= 1/32 × 1/256 - ( 1/7 )^-1​

= 1/32 × 1/256 - 7

= 1/32 × 1/256 - 7

= 1/8192 - 7

= -57343/8192
