Question

What is the definition of "standard form"?

Answer 1

Definition of Standard form:

Standard form is a way where a number can be written as a product of a decimal number between $1.0$ and $10.0$ and powers of $10$.

Example:

Write $7290000000000$ in standard form:

$7290000000000=7.29\times {10}^{12}$

Hence, $12$ means that the decimal point was moved $12$ times.
