Multiple Choice

Use scientific notation to solve the problem.
-Suppose that we could somehow capture all the energy released by the Sun in just one second. For how many years could U.S. energy needs be met by this energy? Assume that the annual energy Generation of the Sun is $1 \times 10 ^ { 34 }$ joules and that U.S. annual energy consumption is 1 $1 \times 10 ^ { 20 }$ joules.
