Question

1.78E12 is a mathematical notation called scientific notation. It represents a very large number in a compact form. In this case, "E" stands for "times 10 raised to the power of", and the number after "E" (12) represents the power of 10 by which the first part (1.78) should be multiplied.

So, 1.78E12 means that the number displayed on Charlee's calculator is equal to 1.78 multiplied by 10 raised to the power of 12. In other words, the actual number is 1.78 followed by 12 zeros: 1,780,000,000,000. smilfyed

Answer 1

1.78E12 is scientific notation for a large number. The "E" means "times 10 raised to the power of," and the number after it (12) is the exponent.

So, 1.78E12 means:

1.78 × 10^12

This equals 1.78 followed by 12 zeros:

1,780,000,000,000.
