Answer 1

Respuesta:

10 : (3 + 2) + (15 + 3) : 3 =  10 : 5 + 18 : 3 = 2 + 6 = 8

(5 + 2) . 3 – 3

2

+ (5 + 4)3

=  7 x 3 – 9 + (9)3

= 21 – 9 + 729 = 741

3 . (1 + 4) + 5 . (2 + 1)2

=  3 x 5 + 5 x (3)2

= 15 + 5 x 9 = 15 + 45 =

60

(3 + 2)2 + (5 . 2)2

– 20 =  (5)2

+ (10)2

– 20 = 25 + 100 – 20 = 105

√

40 – 4 . 5 + (12 + 5 – 2) . 6 =  3 + 40 – 20 + 15 x 6 = 43 – 20 + 90 =

113

√ + 52

– 4 . (3 + 5 – 2) =  10 + 25 – 4 x 6 = 35 – 24 = 11

( ) ( )  24 x 1 + 6 x 9 – 9 = 24 + 54 – 9 = 69

2) Hallar el valor de las siguientes expresiones:

24 – [8 + (9- 2) + 5] – 4 =  24 – 20 – 4 = 24 – 24 = 0

(3 + 5) – [8 – (3 + 4)] =  8 - [8 – 7] = 8 – 1 = 1

47 – [50 – (20 – 2) + (20 + 3) -

13]=

 47 – [50 – 18 + 23 - 13]= 47 – 50 + 18 – 23 + 13

= 5

12 – 8 + 3 – 5 =  (12 + 3) – (8 + 5) = 2

3) Verificar que:

45 – [57 – (31 – 15) – 40] = [ 70 – (18 + 10 - 2)]

45 – [57 – 16 – 40] = [ 70 – (18 + 10 - 2)]

45 – 1 = 70 – 26

44 = 44

(8 – 3) + (9 – 5) + (10 – 6) = (8 + 9 + 10) - ( 3 + 5 + 6)

5 + 4 + 4 = 27 – 14
