Question

cine mă poate ajuta sa pot face ex.??Măcar câteva vă rog!

Answer 1

g) 2^10*a -2^9*b = 2^9*(2a-b) = 2^9*17

h) 2^4*5-2^3*3-2^2*13 = 2^2 (2^2*5-2*3-1*13) = 2^2 (20-6-13) = 2^2 = 4

j) (7^6 - 7^4):48 = (7^4(7^2-1):48) = 7^4*48:48 = 7^4

k) (2^14 + 2^14) : 2^15 = (2^14(1+1):2^15 = (2^14*2):2^15 = 2^15 : 2^15 = 1
