Question

What is 0.000000023 expressed in scientific notation?

Answer 1

Answer:
`2.3 * 10^-8`

Explanation:

Scientific notation is written in the form
`a * 10^b` where b is the integer and the coefficient "a" is a non-zero number between 1 and 10 in absolute value.

In order to expressed it into scientific notation, you can follow these steps:

1) Move the decimal 8 times to the right in the number so that the resulting number, m = 2.3 is greater than or equal to 1 but less than 10

2) Due to the fact that we moved the decimal to the right, it makes the exponent n to be negative. Thus we have n = -8

3) Now let's write it in the scientific form using
`m * 10^n` which equals to
`2.3 * 10^-8`

Happy to help! All the best this semester!
