Answer:
The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27 /125 of a volt and has been reduced 3 times.
Write the voltage in exponential form.
What was the original voltage in the circuit?
Explanation:
voltage = v
v³ - exponential form
v³ = 27/125
make v³ a fraction so v³/1 then cross multiply
so... 125v³ = 27 then v³ = 27/125 or v³ = 0.216 if you like decimals better then to get v by it self you cube root mean v = ∛27/125
original voltage in circuit - v = ∛27/125
