2. Relevant equations

Req = R1R2 / R1+ R2

P = V^2 / R

Thanks you for your time.

3. The attempt at a solution

I am not understanding what they meant by "seem by the source"

so I assume that they want to find R equivalent for the whole thing.

Start from the right to left

2Ω + 1Ω = R_{eq1}= 3Ω

R_{eq1}|| 3Ω = R_{eq2}= 1.5Ω

4Ω + 1.5Ω+5Ω || 6Ω = R_{eq3}= 3.82Ω

---->R_{eqS}= 3.82Ω + 7Ω = 10.82Ω

---->P_{s}= V_{s}^{2}/ R_{eqS}= 18.11 W
