Answer: D) 1.6 x 10^(-7)
Explanation:
The more negative the exponent is, the smaller the number will be. This is only for numbers in scientific notation (which A through D is presented as such).
A positive exponent means move the decimal point to the right. A negative exponent tells us to move the decimal point to the left.
- 1.6 *10^(-3) = 0.0016 moving 3 spots to the left
- 1.6 * 10^(-5) = 0.000016 moving 5 spots to the left
- 1.6 * 10^2 = 160 moving 2 spots to the right
- 1.6 * 10^(-7) = 0.00000016 moving 7 spots to the left
Choice D is the one that moves furthest to the left of all the answer choices.
