We can break this problem down into two questions.

- What is 47.1 x 10
^{6}equal to? - Is 47,800,000 > 47.1 x 10
^{6}?

To answer #1, we can see that 10^{6} = 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000.

So, the problem becomes: 47.1 x 1,000,000 = 47,100,000.

Then, to answer #2, we notice that 47,800,000 is larger than 47,100,000.

Therefore, Taylor Swift has more Facebook fans than Selena Gomez.
