FAQs
Why is 2^10 equal to 1024 and not 1000?
2^10 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 1024 exactly. In computing, 1024 bytes is called a kilobyte, which is close to but not exactly 1000.
What is scientific notation and how do powers of 10 help?
Scientific notation expresses numbers as a decimal between 1 and 10 multiplied by a power of 10. For example, 5000 = 5 x 10^3. Powers of 10 show the magnitude of numbers.
