Question

Calculati:

2^{3} + 2^{10} : 2^{8} x 2 + 2 x 2^{7} : 2^{5} + 2^{10} : (3 x 2^{5} + 2^{5}) - 4 x 2^{3} =


Urgent.

Answer 1

2³ + 2¹⁰ : 2⁸ x 2 + 2 x 2⁷ : 2⁵ + 2¹⁰ : ( 3 x 2⁵ + 2⁵ ) - 4 x 2³ = 120

= 2³ + 2 ⁽ ¹⁰ ⁻ ⁸ ⁺ ¹ ⁾  + 2 ⁽ ¹ ⁺ ⁷ ⁻ ⁵ ⁾  + 2 ¹⁰ : 2⁵ x ( 3 + 1 ) - 2² x 2³ =

= 2³ + 2³ + 2³ + 2 ⁽ ¹⁰ ⁻ ⁵ ⁾ x 2² - 2² x 2³ =

= 2³ + 2³ + 2³ + 2 ⁽ ⁵ ⁺ ² ⁾  - 2² x 2³ =    ( 2 ⁷ = 2³ x 2⁴ )

= 2³ x ( 1 + 1 + 1 + 2⁴ - 2² ) =

= 8 x ( 3 + 16 - 4 ) =

= 8 x 15 =

= 120
