How would you enter a 120,000 Ohm resistor into a calculator using scientific notation?

To express 120,000 Ohms in scientific notation, the goal is to represent it as a number between 1 and 10 multiplied by a power of ten.

Starting with 120,000, you can convert this number into scientific notation by moving the decimal point five places to the left, giving you 1.2. This results in the base number of 1.2. Since you moved the decimal left by five places, this corresponds to multiplying by 10 raised to the power of 5. Therefore, you write it as 1.2 x 10^5.

This format clearly communicates the value while adhering to the conventions of scientific notation, where only one non-zero digit appears to the left of the decimal point. Thus, 1.2 x 10^5 accurately represents 120,000 Ohms in a concise way suitable for calculations.
