Question

ex 8 va rog repede
dau coroana

Answer 1

a) 3^21 x ( 1 + 1 + 1) = 3^21 x 3 = 3^22

b) = 6 x 6^28 = 6^29

c) = 4 x 2^29 = 2^2 x 2^29 = 2^31

d) = 5^3 x 1 : 5^2 + 3^12 : 3^12 = 5^3 : 5^2 + 1= 5 + 1 = 6

e) = (7^6 : 7^5 + 7^2) : 7 = (7 + 7^2) : 7 = (1 + 7) = 8

f) 8^12 : 2^36 x (2^60 : 2^50) = (2^3)^12 : 2^36 x 2^10 = 2^36 : 2^36 x 2^10 = 2^10

g) = 2^(1 + 2 + 3 + 4 + 5) = 2^15

h) = 2^(1 + 2+ 3 + ....+ 2004) = 2^(2004x2005/2) = 2^ 1002x2005 = 2^2009010
