Two ways to do it. In this particular problem, it's a matter of opinion
which one is easier and which one is harder.
Way #1:
Convert dBm to watts, multiply by gains, convert output watts to dBm.
+20 dBm = 0.1 watt.
Output power = (0.1 watt) x (ap1) x (ap2) x (ap3) = 0.1 x 10 x 4 x 23 = 92 watts = +49.64 dBm
Way #2:
Convert each gain ratio to dB, then add all dB to input power.
ap1 = 10 = 10 dB
ap2 = 4 = 6.02 dB
ap3 = 23 = 13.62 dB
+20 dBm + 10dB + 6.02 dB + 13.62 dB = +49.64 dBm

Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
What is the definition of input number?
The definiton of input number is the number going in. The input number is the oppsite of the output number. For instance:Input Output1 52 103 154 205 25The rule of the input and output number is input times five equals output.
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
The value that results from the substitution of a given input into an expression or function?
The value that results from the substitution of a given input into an expression or function is the output. The value substituted into an expression or function is an input.
If a given input value yields four output values that relationship can be best described as a relation true or false?
This is true. If a given input value yields four output values that relationship can be best described as a relation.
Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
What is the name for the level of crop output from a given level of input?
Productivity
Does energy input always equals energy output?
Yes it does
What is released as one form of energy changes to another form?
Energy. Given that energy can be neither created nor destroyed, the total energy output equals that input, and in a system the ratio of that output energy desired to the total input gives the efficiency.
What is the output of voltage follower?
same as the given input..
What is the definition of input number?
The definiton of input number is the number going in. The input number is the oppsite of the output number. For instance:Input Output1 52 103 154 205 25The rule of the input and output number is input times five equals output.
What is an open loop?
Output is obtained for a given input and we cant control the output my means of any feedback loop control to the input

Productivity
How do you find speed ratio?
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
How do you use a graph to find the output value of a linear function for a given input value?
You how to remember input and output is like a machine do the rest.
What is the function of the IC 7404?
It will give high output when the given input is low and also give LOW output when the given input is high (Vice versa).
What is the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
