Answer 1

a) 3.10² + 4.10³ = 3.100 + 4.1000 = 300 + 4000 = 4300

b)3.10² x 4.10³ = 3.100 x 4.1000 = 300 x 4000 = 1.200.000

c)5.104x 8.105= 520 x 840 = 436.800

d)8.106÷4.10³ = 8.106 ÷ 4.1000 = 848 ÷ 4000 = 0,212

e)4.10² + 5.10³ = 4.100 + 5.1000 = 400 + 5000 = 5400

f)6.104x 4.102 = 624 x 408 = 254.592

g)3.103x 7.106 = 309 x 742 = 229.278

h)15.106÷3.10³ = 15.106 ÷ 3.100 = 1590 ÷ 3000 = 0,53

i)24.1027÷ 6.109 = 24648 ÷ 654 = 37,68...
