The correct answer is 3.28 × 10^12.
The correct option is 3.28×10^12.
To understand scientific notation, we need to know that it is a way to express very large or very small numbers using powers of 10. In scientific notation, a number is written as the product of a coefficient (between 1 and 10) and a power of 10.
In this case, the number displayed on the calculator is 3.28E12. The "E" represents "times 10 raised to the power of." So, 3.28E12 means 3.28 times 10 raised to the power of 12 (3.28×10^12). Therefore, the answer is 3.28×10^12.
