Question

(2^2017-2^2016-^2015):2^5

Answer 1

Răspuns:

Explicație pas cu pas:

( 2²⁰¹⁷ - 2²⁰¹⁶ - 2²⁰¹⁵ ) : 2⁵ =

= 2²⁰¹⁵ x ( 2² - 2 - 1 ) : 2⁵ =

= 2²⁰¹⁵ x 1 : 2⁵ =

= 2⁽²⁰¹⁵⁻⁵⁾ =

= 2²⁰¹⁰

Answer 2

( 2 ^ 2017 - 2 ^ 2016 - 2 ^ 2015 ) : 2 ^ 5 =

2 ^ 2015 × ( 2 ^ 2 - 2 ^ 1 - 1 ) : 2 ^ 5 =

2 ^ 2015 × ( 4 - 2 - 1 ) : 2 ^ 5 =

2 ^ 2015 × ( 2 - 1 ) : 2 ^ 5 =

2 ^ 2015 × 1 : 2 ^ 5 =

2 ^ 2015 : 2 ^ 5 =

2 ^ ( 2015 - 5 ) = 2 ^ 2010
