In government class, Nadia computed the amount of debt of the federal government after a third of it was paid in 1995. The calculator displayed the number 3.28E12. What is this number in scientific notation?

Question

3.28×10−12
3.28 times 10 superscript negative 12 baseline

3.28×1012
3.28 times 10 superscript 12 baseline

3.28+1012
3.28 plus 10 superscript 12 baseline

12×103.28

Answer 1

The number displayed on Nadia's calculator, 3.28E12, is in scientific notation. The "E" stands for "exponent," so 3.28E12 means \(3.28 \times 10^{12}\).

Thus, the correct interpretation of this number in scientific notation is:

3.28 × 10¹² (which is represented as 3.28 times 10 superscript 12 baseline).
