Answer 1

a) (10*3x10*7)*2 pastram baza si facem 7x3: (10*21)*2. 21x2: 10*42. b)(21x21*49):(49*5)*3= daca ai ca in situatia asta 21x21*49. 21 se considera 1 deci este 21*50:49*15 si acum cred ca ar trebui sa ii dai factor comun restul te descurci?

Answer 2

a) (10^3 × 10^7)^2 : (25^2)4

(10^10)^2:25^8

10^20:25^8

10^20 supra 25^8

b) (15^4×15^6)^4 : (27^3)^2

(15^10)^4 : 27^6

15^40 : 27^6

15^40 : 27^6

15^40 supra 27^6

c) (21×21^49)^2 : (49^5)^3

(21^50)^2 : 49^15

21^100 : 49^15

21^100 supra 49^15

d) (14×14^14)^4 : (64^3)^2

(14^15)^4 : 64^6

14^60 : 64^6

14^60 supra 64^6
