Question

How do you write `8.5 times 10^(-7)` in standard form?

Answer 1

already in standard form

Explanation:

To express a number in standard form we write it as follows:

`axx10^n" where " 1≤a<10" and n is an integer"`

`8.5xx10^-7" is in this form"`

In case you are asking for the original number.

Then the `color(blue)" -7"` from the index of the 10 , lets us know to move the decimal point 7 places to the left from where it has been placed between the 8 and 5.

`rArr8.5xx10^-7=0.00000085`
