Question

How do you convert -52,300,000 into scientific notation?

Answer 1

The number in standard scientific notation is `-5.23× 10^7`.

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 `"-52,300,000"`.

The negative sign remains unchanged.

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, `"-52,300,000"` becomes `"-5.230,0000"`.

The trailing zeroes are not significant, so `"-5.230,0000"` becomes `-5.23`.

We moved the decimal point seven places, so the exponent is `7`.

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

The exponential part is therefore `10^7`.

`"-52,300,000" = -5.23 × 10^7`
