b) 3.10² x 4.10³ =

12.10^5=>1.200.000

c) 5.104=>520

x 8.105=>840

= _________

d) 8.106=>848

x 4.10³ =>4000

e) 4.10² x 5.10³ =20.10^5=>2.000.000

f) 6.104=>624

x 4.102=>408

= _________

g) 3.103=>309

x 7.106=>742

= _________

h) 15.106=>1590

I) 3.10³ =3.000

Answer 2

a) 3.10² x 4.10³ = 12. 10^5

b) 3.10² x 4.10³ = 12.10^5

c) 5.10⁴ x 8.10^5 = 40.10^9

d) 8.10^6 x 4.10³ = 32.10^9

e) 4.10² x 5.10³ = 20.10^7

f) 6.10^4 x 4.10²= 24.10^6

g) 3.10³ x 7.10^6= 21.10^9

h) 15.10^6 x 3.10³ = 45.10^9
