Question

How do you write $673.5$ in scientific notation?

Answer 1

Write $673.5$ in scientific notation.

By definition, scientific notation is expressed in the form of $a\times {10}^n$ where, $10>a>1$ and $n$ is an integer.

Hence, we need to move the decimal point $2$ places to the left so the exponent for the $10\text{'}\text{s}$ term will be positive:

$673.5=6.735\times {10}^2$

Thus, the scientific notation for $673.5$ is $6.735\times {10}^2$.
