\(215 = 2. 10^2 + 1. 10^1 + 5. 10^0\)
\(902 = 9.10^2 + 0.10^1+ 2 . 10^0\)
\(2 020 = 2.10^3+0.10^2+2.10^1+0. 10^0\)
\(883 001 = 8.10^5+8.10^4+3.10^3+0.10^2+0.10^1+1. 10^0\)
a) 215=2.10^2+1.10+5
b) 902=9.10^2+2
c) 2020=2.10^3+2.10
d) 883001=8.10^5+8.10^4+3.10^3+1
\(a)\)\(215=2.10^2+1.10+5\)
\(b)\)\(902=9.10^2+2\)
\(c)\)\(2020=2.10^3+2.10\)
\(d)\)\(883001=8.10^5+8.10^4+3.10^3+1\)
\(215=2\cdot10^2+1\cdot10+5\cdot10^0\)
\(902=9\cdot10^2+2\cdot10^0\)
\(2020=2\cdot10^3+2\cdot10\)

215=2.102 + 1.10 + 5
902 = 9.102 + 0.10 + 2
2 020 = 2.103 + 2.10 + 0
883 001 = 8.105 + 8.104 + 3.103 + 1
