Final answer:
The student's question involves converting IEEE floating point numbers to decimal equivalents and expressing numbers in scientific notation by adjusting the decimal point to show the correct significant figures.
Step-by-step explanation:
The student has asked to write the decimal equivalents for several IEEE floating point numbers and to express other numbers in scientific notation. Writing numbers in scientific notation involves expressing them as the product of a number between 1 and 10 and a power of 10. It is used to easily represent very large or very small numbers.
- For the number 8,099 x 107, it should be written in scientific notation as 8.099 x 1011.
- The number 34.5 x 100 is already in scientific notation as 3.45 x 101.
- For the number 0.000332 x 104, it should be written as 3.32 x 100.
To express the given numbers in scientific notation by counting the number of places the decimal point is moved:
- For 123,456.78, the scientific notation is 1.2345678 x 105.
- The number 98,490 is 9.8490 x 104.
- For 0.000000445, it is 4.45 x 10-7.
