Why would you write a number in exponents instead of standard notation?

Answer 1

Writing a number in exponents usually becomes necessary in higher level mathematics. This is also necessary when the number of exponents becomes too great to reasonably fit.

Answer 2

Writing a number in exponent form is useful when dealing with very large or very small numbers. It allows for a more compact representation of the number, making calculations and comparisons easier. Additionally, it simplifies mathematical expressions and can convey information about significant figures or decimal places in a concise manner.
