Math Help - find R_AB

1. find R_AB

find $R_{ab}$

first I added $5\Omega + 5\Omega = 10\Omega$

then $\frac{10\Omega\times10\Omega}{10\Omega+10\Omega}=5 \Omega$

then $\frac{8\Omega\times8\Omega}{8\Omega+8\Omega}=4\Ome ga$

so $4\Omega+ 5\Omega+ 1\Omega = \boxed{1\Omega}$

2. I'm not sure, either. It should be

$4\Omega+ 5\Omega+ 1\Omega = \boxed{10\Omega}.$

Everything else looks ok, though.

3. sorry typo

but haven't learned how to add or subtract numbers yet...
