Answer:

The number in standard scientific notation is #3.2 × 10#.

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 #32#.

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, #32# becomes #3.2#.

We moved the decimal point one place, so the exponent is #1#.

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

The exponential part is therefore #10^1#.

The exponent "1" is not usually written, so #10^1 = 10#.

So #32 = 3.2 × 10#.
