Write in scientific notation quick check

1 answer

Scientific notation is a way of writing numbers that are very small or very large in a compact form. It is expressed as a number between 1 and 10 multiplied by a power of 10.

To write a number in scientific notation, move the decimal point so that there is only one non-zero digit to the left of it. Count the number of places you moved the decimal point. If you moved it to the left, the power of 10 is positive. If you moved it to the right, the power of 10 is negative.

For example, the number 500,000 can be written in scientific notation as 5 x 10^5. The decimal point was moved 5 places to the left, so the power of 10 is positive 5.

On the other hand, the number 0.00003 can be written in scientific notation as 3 x 10^-5. The decimal point was moved 5 places to the right, so the power of 10 is negative 5.

Scientific notation is useful in expressing very large or very small numbers, as it simplifies calculations and makes comparisons easier.
