A vitamin powder weighs 0.0002 pound.
The container holding the powder weighs
0.006 pound. What is the total weight
of the vitamin powder and container,
written in scientific notation?
A. 6.2 X 10 ^-3 pound
B. 2.6 x 10 ^-3 pound
C. 6.2 X 10 ^-4 pound
D. 2.6 X 10 ^-4 pound

First, you have to find the total weight by adding 0.0002 and 0.006 together, which gives you 0.0062. Then, follow basic setup of scientific notation by moving the decimal until one non-zero digit is to the left of the decimal, which brings the decimal to 6.2. Since you are moving the decimal right three places, the exponent is negative 3, making the notation 6.2 X 10 ^-3
