Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation. Fn = F1 + (F2 - 1 / G1) + (F3 - 1 / G1G2) + (F4 - 1 / G1G2G3) ....... and so on Where: Fn = The total noise of all stages together F1 = The noise factor of stage 1 F2 = The noise factor of stage 2 F3 = The noise factor of stage 3 G = Gain of respective stage Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation.

It is an equation. It could be an algebraic equation, or a trigonometric equation, a differential equation or whatever, but it is still an equation.
Simply that, an "equation".Simply that, an "equation".Simply that, an "equation".Simply that, an "equation".
you don't answer an equation, you solve an equation
A logarithmic equation would be any equation that includes the log function.
