Answer 1

A) 4500= 4,5 x 10^3

B) 0, 0080= 8,0 x 10^-3

C) 225, 2.10^2= 2,255 x 10^4

D)0,080.105^5= 8,0 x 10^-2 x 1,05 x 10^7 = 8,4 x 10^5

E)15.10^5+0,3.10^4 = (15 x 0,3) x 10^4+5 = 4,5 x 10^9

F)2,2.10^5+0,3.10^-2 = (2,2 x 0,3) x 10^5-2 = 0,66 x 10^3 = 6.6 x 10^2

G)5,25.10^-3- 0,2.10^-2 = (5,25 x 0,2) x 10^-3-2 = 1,05^-5

H) 34.10^8- 64.10^8 = (3,4 x 6,4) x 10^9+9 = 21,76 x 10^18 = 2,176 x 10^19

I) 45.10-3.210^8 = (4,5 - 2) x 10^-2+8 = 2,5 x 10^7
