Question

Watts are units that measure the rate at which energy is used. A kilowatt is equal to 10 to the 3rd power watts. A gigawatt is equivalent to 10 to the 9th power watts. How many kilowatts are in a gigawatt?

Answer 1

`\begin{gathered} 1GW=10^(10)W \\ \text{but }1W=10^(-3)KW \\ \text{therefore} \\ 1GW=10^(10)\cdot10^(-3)KW=10^7KW \end{gathered}`
