Answer:
1. Every zero is basically
[tex] {10}^{1} [/tex]
For example
[tex] {10}^{1} = 10 \\ {10}^{2} = 100 \\ {10}^{3} = 100 \: \\ etc[/tex]
2.
[tex]when \: using \: 138 \: the \: scientific \: \\ is \: 1.38 \times {10}^{2} \: because \: ... \: see \: previous \\ \: example \: . \: the \: 1.38 \: is \: created \: due \: to \\ \: 138 \: being \: divided \: by \: 100 \: resulting \\ in \: 1.38[/tex]
3.
[tex]the \: x \: in \: {10}^{x} \: is \: always \: equivalent \\ to \: the \: amount \: of \: zeros \: in \: the \: number \\ for \: example \: 100 = {10}^{2 } \\ 0.01 = {10}^{ - 2} [/tex]
