Charlee is using her calculator to find the product of two large numbers. Her calculator shows 1.78E12 on display. Interpret what this means

Answer 1

The notation "1.78E12" is a scientific notation used to represent very large or very small numbers. In this case, "1.78E12" means \(1.78 \times 10^{12}\).

To interpret this:

1. The number 1.78 is the significant figure.
2. The "E12" indicates that the decimal point in the number 1.78 should be moved 12 places to the right.

Therefore, the value of 1.78E12 is:

\[ 1.78 \times 10^{12} = 1,780,000,000,000 \]

This means that the product of the two large numbers Charlee was calculating is 1,780,000,000,000, which is one trillion, seven hundred eighty billion.
