How do you write numbers without zeros in scientific notation?

To write numbers without zeros in scientific notation, first express the number in standard form by placing the decimal point after the first non-zero digit. Then, count how many places the decimal has moved to determine the exponent on 10. For example, the number 12345 becomes 1.2345 × 10^4, while 0.00456 becomes 4.56 × 10^-3. This format preserves the significant digits without using zeros.
