First, divide 100 by 83.06.

On a calculator, you'll enter: 100 ÷ 83.06 =

This gives you approximately 1.2039499157...

Raise the result to the power of 1/4:

Most calculators have a y^x or ^ button for exponents. You'll need to use parentheses for the fraction in the exponent.

Enter: (your previous result) ^ (1 ÷ 4)

For a scientific calculator, it would look like this: 1.2039499157... ^ (1 / 4) =

This simplifies the exponent to 0.25. So, you can also enter 1.2039499157... ^ 0.25 =

This gives you approximately 1.04743236...

Take the result from the previous step and subtract 1.

Enter: 1.04743236... - 1 =

This gives you approximately 0.04743236

The final answer is approximately 0.0474.
