Ta có:
a)
$10^{2}=10.10=100$
$10^{3}=10^{2}.10=100.10=1000$
$10^{4}=10^{3}.10=1000.10=10000$
$10^{5}=10^{4}.10=10000.10=100000$
$10^{6}=10^{5}.10=100000.10=1000000$
b)
$1000=10^{3}$
$1000000=10^{3}.10^{3}=10^{3+3}=10^{6}$
1 tỉ = $1000000000=10^{6}.10^{3}=10^{6+3}=10^{9}$
100...0 ( 12 chữ số 0 ) = $1000000000000=10^{12}$
