Answer:

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

Explanation:

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#
