Question

How do you convert 32 into scientific notation?

Answer 1

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`.
