Question

How do you write `0.00000124` in scientific notation?

Answer 1

`1.24 xx 10^-6`

Explanation:

In scientific notation the value of the number is expressed as a decimal with one digit in the ones place and the other significant digits written to the right of the decimal. Then this decimal is multiplied by a power of 10

In the problem above the decimal point needs to be moved six places to the right. This is the same as dividing by 1,000,000 or
`10^6`

`1/(1,000,000) = 10^-6` a negative exponent is an expression of dividing.
