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
1.78E12 is scientific notation for 1.78 multiplied by 10 to the power of 12. In other words, the actual number is 1.78 followed by 12 zeros. So, the product of the two large numbers that Charlee is calculating is 1.78 with 12 zeros after it.
A 1.78 with twelve zeros behind it would be written as:
1,780,000,000,000
The number 1.78E12 is written in scientific notation. In scientific notation, "E" represents "times 10 to the power of". Therefore, 1.78E12 means 1.78 multiplied by 10 to the power of 12. In decimal form, this is equivalent to 1,780,000,000,000. So, Charlee's calculator is displaying the product of the two large numbers as 1,780,000,000,000.
The value displayed on Charlee's calculator, 1.78E12, is in scientific notation. In scientific notation, a number is represented as a coefficient multiplied by 10 raised to a certain power.
Here, the coefficient is 1.78, and the power of 10 is 12. So, 1.78E12 can be interpreted as 1.78 multiplied by 10 raised to the power of 12.
To express it in standard decimal form, you would multiply 1.78 by 10 raised to the power of 12:
1.78 × 10^12 = 1,780,000,000,000
Therefore, the product of the two large numbers Charlee is working with is 1,780,000,000,000.
