    \[ \color{green}{3.82}\color{cyan}{e}\color{red}{{+7}}=\color{green}{3.82}\times\color{cyan}{10}^\color{red}{7}\\ \text{Another example:}\\ \color{green}{5.34}\color{cyan}{e}\color{red}{{-3}}=\color{green}{5.34}\times\color{cyan}{10}^\color{red}{-3}\\ 3.82e{+7}=3.82\times10^7=3.82\times\underbrace{10,000,000}_{\text{7 zeros}} \]

    Unless your teacher specified to write it in this form, don't write numbers like this \( 5.34e{-3} \). Write this: \(5.34\times 10^{-3}\). Teachers don't like students to be lazy although they probably are!
