Question

17Calculati d). { [ (12^2+5^2):13]^2-2^7-2^0}:2^3
​

Answer 1

Răspuns:

5

Explicație pas cu pas:

{[(12² + 5²) : 13]² - 2⁷ - 2⁰} : 2³ =

= {[(144 + 25) : 13]² - 128 - 1} : 8

= [(169 : 13)² - 129] : 8

= (13² - 129) : 8

= (169 - 129) : 8

= 40 : 8

= 5

Answer 2

{[(12²+5²):13]²-2⁷-2⁰}:2³=

={[(144+25):13]²-128-1}:8=

=[(169:13]²-129]:8=

=(13²-129):8=

=(169-129):8=

=40:8=5
