The number in standard scientific notation is $7.27 × 10^2$ .

In scientific notation, numbers are written in the form $a × 10^b$ , where $a$ is the "pre-exponential" part and $10^b$ is the "exponential part".

Your number in decimal form is $727$ .

To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point.

So, $727$ becomes $7.27$ .

We moved the decimal point two places, so the exponent is $2$ .

We moved the decimal point to the left, so the exponent is positive.

The exponential part is therefore $10^2$ .

$727 = 7.27 × 10^2$
