Charlee is using her calculator to find the product of two large numbers. Her calculator shows 1.78E12 on the display. Interpret what this means. (2 points)

1 answer

The notation "1.78E12" is a way to express a number in scientific notation. It means that the number is \( 1.78 \times 10^{12} \). This indicates that the value displayed on Charlee's calculator is 1.78 multiplied by 10 raised to the power of 12.

In standard form, this is equivalent to:

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

Therefore, the calculator is showing that the product of the two large numbers is 1.78 trillion, or 1,780 billion.
