\(2013=2.1000+10+3=2.10^3+1.10^1+3.10^0\)
\(20112013=2.10000000+100000+10000+2.1000+10+3\)
\(=2.10^7+10^5+10^4+2.10^3+10^1+3.10^0\)
2013 = 2 x 1000 + 10 + 3 = 2 x 10^3 + 1 . 10^1 + 3 . 10^0
20112013 = 2 x 10000000 + 100000 + 2 x 1000 + 10 + 3 = 2 x 10^7 + 10^5 + 10^4 + 2 x 10^3 + 10^1 + 3 x 10^0
ok nhé với lại 10^2 là 10 mũ 2 nhé =>
987 = 900 + 80 + 7
= 9.100 + 8.10 + 7
= 9.102 + 8.101 + 7.100
2564 = 2000 + 500 + 60 + 4
= 2.1000 + 5.100 + 6.10 + 4
= 2.103 + 5.102 + 6.101 + 4.100
= a.10000 + b.1000 + c.100 + d.10 + e
= a.104 + b.103 + c.102 + d.101 + e.100
538 = 5 . 100 + 3 . 10 + 8 = 5 . 102 + 3 . 101 + 8 . 100
(abcd) = a . 1000 + b . 100 + c . 10 + d = a . 103 + b . 102 + c . 101 + d . 100
538= 10^2+10^2+10^2+10^2+10^2+10^1+10^1+10^1+1+1+1+1+1+1+1+1
538=5.100+3.10+8.1=5.102+3.101+8.100
abcd=a.1000+b.100+c.10+d.1=a.103+b.102+c.101+d.100
538 = 5 . 102 + 3 . 10 1 + 8 . 10 0
abcd = a . 103 + b . 102 + c . 101 + d . 100
\(135=1.10^2+3.10+5\)
\(2468=2.10^3+4.10^2+6.10+8\)
k cho mình nhé !
135=10^2+3.10+5.10^0
2468=2.10^3+4.10^2+6.10+8.10^0
k mik nhé
