Answer 1

Respuesta:

a) (2x10-6) (4x10-2)=  (20 - 6) (40 - 2) = 14 * 38 = 532

b) (3,73 x10-1) (1,2x102) =  (37,3 - 1) ( 122,4) = 36,3 * 122,4 = 4443,12

c) (1,365x1022) : (6,5x1015) =  (1395,03) / (6597,5‬) = 0,21144827586206896551724137931034 ≈ 0,211

d) (1,431x103) : (5,4x105) =  147,393 / 567 = 0,25995238095238095238095238095238 ≈ 0,260

e) (5,43x1012) (8,2x10-5)=  (5495,16) (82 - 5) = 5495,16 * 77 = 423127,32

f) (6,2x10-15) (1,8x10-13)=  (62 - 15) (18 - 13) = 47 * 5 = 235

g) (3,4x107) : (8,1x10-6)=  (363.8) / (81 - 6) = 363.8 * 75 = 27285

h) (8,2x10-7) : (4,5x106)=  (82 - 7) (477) = 75 * 477 = 35775

i) (1,4x10-7) : (5x10-6)= (14 - 7) (50 - 6) = 7 * 44 = 308
