Question

URGENT VA ROGGG!!!!!!​

Answer 1

Răspuns:

1.

a)

${5}^{3} - {2}^{4}$

125-2 la puterea a4a =

125-16=

109

b)

${123}^{0 -} {1}^{2012}$

1-1 la puterea 2012 =

1-1=

0

c)

${5}^{2} \times {2}^{2}$

25-2 la puterea a2a =

25-4=

21

d)

(2+9) la puterea a2a

11 la puterea a2a =

121

5.

57 : 2 = 28 rest 1

28 : 2 = 7 rest 0

14 : 2 = 3 rest 0

3 : 2 = 1 rest 1

1 : 2 = o rest 1

57 = 111001 (baza 2 )

la restul cred ca te ajuta ceilalți :) succes
