Question

15. convert the following values into scientific notation, a) 42,670,000 B) 0.0000008

Answer 1

Answer:

8x10^-7

Step-by-step explanation:

First one you have correct however the second one you were close lets figure it out:

0.0000008

In order to move the decimal in front of the eight we have to "jump" 7 times to the right.  Furthermore since we have to move the decimal to the right our exponent will be negative.  That means that we have:

$0.0000008=8 \times 10^{-7}$
