Answer 1

a) $2*10^3 = 2*(10*10*10)=2000$

b)$1,2*10^6= 1,2*(10*10*10*10*10*10)=1.200.000$

c)$7,5*10^2= 7,5*(10*10)=750$

d)$8*10^5=8*(10*10*10*10*10)=800.000$

Espero ter ajudado.

Answer 2

a)2.10^3=2(10.10.10)=2.1000=2000

b)1,2.10^6=12.10^5=12(10.10.10.10.10)=12.100000=1200000

c)7,5.10^2=75.10^1=75.10=750

d)8.10^5=8(10.10.10.10.10)=8.100000=800000
