say... lemme show a few... examples....
usually the Zeros are NOT significants if they aren't between other non-zero digits

say \(\bf 0.00{\color{red}{ 735}}\qquad \textit{3 significant digits}\\
{\color{red}{ 735}}.00\qquad \textit{3 significant digits}\\
{\color{red}{ 7035}}.0\qquad \textit{4 significant digits}\\
0.0{\color{red}{ 7305}}\qquad \textit{4 significant digits}\\
{\color{red}{ 1}}00000\qquad \textit{1 significant digits}\\
{\color{red}{ 1001}}000\qquad \textit{4 significant digits}\)
