Question

9. Brenna wants an easier way to write 0.0000000000000000587.

0.0000000000000000587 is written as______
x 10____
in scientific notation.

Answer 1

5.87 x
`10^(-17)`

Explanation:

You need to write the number as 1 or larger than 1, but less than 10. That means that I need to put the decimal between the 5 and the 8. Now I have to count how many places I moved the decimal. I think that I counted right. It was moved 17 places. Since the number in standard form is much smaller than 5.87, the exponent will be negative.
