Answer 1

Resposta:

a) 6x 10^{5}+ 23 x 10^{5} = 29 x 10^{5} = 2.900.000

b) 34x 10^{9} – 9 x 10^{9} = 25 x 10^{9} = 25.000.000.000

c) 13,5x 10^{4} - 8,3x 10^{4} = 5,2 x 10^{4} = 52.000

d) 45,2x 10^{6} + 17,4x 10^{6}= 62,6 x 10^{6} = 62.600.000

e) 9x 10^{3} x 8x 10^{4} =72 x 10^{7} = 720.000.000

f) 72x 10^{9} : 9x 10^{5} = 8 x 10^{4} = 80.000

g) 4,12x 10^{7} x 2,5x 10^{6} = 10,3 x 10^{13} = 103.000.000.000.000

h) 39x 10^{12} : 13x 10^{8} = 3 x 10^{4} = 30.000
