Q. How do you write

2.8 \times 10^3

in standard form?

\newline

_____

Move Decimal Three Places: To write the number $2.8 \times 10^3$ in standard form, we need to move the decimal point in $2.8$ three places to the right, because the exponent on $10$ is $3$ . This is because $10^3$ means $10$ multiplied by itself $3$ times, which is $1000$ . Multiplying $2.8$ by $1000$ will shift the decimal point three places to the right.
Multiply by $1000$ : Moving the decimal point three places to the right in $2.8$ gives us $2800$ . This is because moving the decimal point one place to the right for each power of ten in $10^3$ results in the number $2800$ .
