dau coroana daca e rezolvare completa :)

Answer 1

Raspunsul e in poza si da e complet. Sper sa intelegi ce am scris.

Answer 2

a)

((-4)²)⁶ : (-4)⁸ : 2³ =

4¹² : 4⁸ : 2³ =

4⁴ : 2³ =

2⁸ : 2³ =

2⁵ = 32

a = 32

b ) (-7)⁵ × (-7)¹² : [( -7)³]⁵ + 13

( -7)⁵ × 7¹² : ( -7)¹⁵ + 13

7² + 13 = 49 + 13 = 62

b = 62

c ) 1 - 2 + 3 - 4 + ......... 19 - 20 =

(1-2) + ( 3 - 4 ) + ...... (19-20) =

- 1 × 10 = - 10

c = - 10

$m.a = \frac{a + b + c}{ 3} = \frac{32 + 62 + ( - 10)}{3} = \frac{84 {}^{(3} }{3} = 28$
