Scientific Notation
Scientific notation is a method of expressing numbers that are too large or too small in a compact form. It is written as the product of a number between 1 and 10 and a power of ten. For example, the number 100,000 can be expressed as 1.0 x 10^5 in scientific notation.

Significant Figures
Significant figures are the digits in a number that contribute to its precision. This includes all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. When converting to scientific notation, it is important to round the number to the specified number of significant figures, which in this case is two.

Rounding Rules
Rounding rules dictate how to adjust numbers to the desired level of precision. When rounding to two significant figures, if the digit following the last significant figure is 5 or greater, the last significant figure is increased by one. This ensures that the representation of the number remains as accurate as possible while adhering to the specified significant figure requirement.
