Question

Please somebody can help me with the problem #12. Thanks.

Answer 1

\[27=3^3\] and \[125=5^3\]

Answer 2

does that help?

Answer 3

yes so the original voltage in the circuit is (3/5)^3,

Answer 4

i think that is the answer to the first part
the "original voltage" is probably just \(\frac{3}{5}\)

Answer 5
