# Calculate transmitting power of the Transmitter

I cannot get a hold of my professor and I'm stuck tyring to understand how to solve this problem. It's not homework or an assignment I'm preparing my self for a test.

So as the title states I need to calculate the transmitting power of the transmitter if we Increase said power? for 20db or 3db.

There is very little explanation in the book about this the first are given and go as follows:

Initial step:
$$dB = 10 \cdot log_{10} \bigg( \frac{P1}{P0} \bigg)$$

First step: $$20dB = 10 \cdot log_{10} \bigg( \frac{P1 + x}{P0} \bigg)$$

Third step:
$$\frac{20dB}{10} = log_{10}\bigg( \frac{P1 + x}{P0} \bigg)$$

That's it only thing that they added was:
P1 = Transmitting power,
P0 = Reference power?

Can anyone please give me a better detailed explanation about this how to solve it. The problem does not provide and information regarding values of P and what the hell is that x in First step.
