Answer 1

Resposta:

1) 0,00000854 x 0,0000134

8,54x10^-6 x 1,34x10^-5

(8,54x1,34 [11,4436] )x(10^-6x10^-5 [10^-11] )

11,4436x10^-11 = 1,14436x10^-10

2) 0,00895 x 0,000536

8,95x10^-3 x 5,36x10^-4

(8,95x5,36 [47,972] ) x (10^-3x10^-4 [10^-7] )

47,972x10^-7 = 4,7972x10^-6

c) 1286 x 123

1,286x10^3 x 1,23 x 10^2

(1,286x1,23 [0,158178] ) x (10^3x+10^2 [10^5] )

0,158178x10^5 = 1,58178x10^4

d) 276 x 28543

2,76x10^2 x 2,8543x10^4

(2,76x2,8543) [7,877868] ) x (10^2x10^4) [10^6] )

7,877868x10^6
