It is necessary to express the power of the power plant in decibels.
I go online and find out that bel is the decimal logarithm of the ratio of two physical quantities, the second of which (the denominator of the fraction) is called a certain base. In the same place on the Internet you can find the corresponding formula for the calculation.
Here's how such a calculation might look like in Mathcad 15 with the help of tools for separating variable and function names into styles using different font colors (black, green, blue and white - invisible).
If one watt is taken as the base, then the power of the largest Russian thermal power plant, Surgutskaya GRES-2, will be 96.812 decibels (see please the picture and the attach).

We solve the inverse problem: given the power in decibels, it is necessary to calculate the power in the usual watts.

Question. Why are decibels called decibels and not decabels? After all, if we multiply the logarithm by ten, and not by one tenth.
