Va rog frumos ajutorr!!​

Answer 1

a) (5² - 2⁵ : 2) : 3 - 1²⁰¹⁹ =

(25 - 32 :2) : 3 - 1 =

(25 - 16) : 3 - 1 =

9 : 3 - 1 =

3 - 1

2

b) (3² • 2⁶ - 2⁵ • 6) : 12 - 2⁵ =

(9 • 64 - 32 • 6) : 12 - 32 =

(576 - 192) : 12 - 32 =

384 : 12 - 32 =

32 - 32 =

0

c) (7⁴ - 7³) : (7² - 7) -2³ • 5 =

(2.401 - 343) : (49 - 7) - 8 • 5 =

2.058 : 42 - 8 •5 =

49 - 40 =

9
