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

538= 500+30+8=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= 5.100 + 3.10 + 8.1 = 5.10^2 + 3.10^1 + 8.10^0
abcd = a.1000 + b.100 +c.10 + d.1 = a.10^3 + b.10^2 + c.10^1 + d.10^0
\(538=5.100+3.10+8.1\)\(=5.10^2\)\(+\)\(3.10^1\)\(+\)\(8.10^0\)
\(abcd=a.1000+b.100+c.10=d.1\)\(=\)\(a.10^3\)+ \(b.10^2\)+ \(c.10^1\)+ \(d.10^0\)
