Never mind,
5 x 9 + 9 x 2 = 3^2 x 9
3 x 2 + 7 x 3 = 27 = 3^3

Thanks!

Hi guys, did you see the explanation?

Column A is 63 = 3^2 · 7 and Column B is 27 = 3^3. The power of 3^3 is larger than the power of 3^2. Hence, Column B is larger.

Hi Nupcia,

3 · 2 + 7 · 3 =
6 + 21 =
27

and

5 · 3^2 + 3^2 · 2 =
5 · 9 + 9 · 2 =
45 + 18 =
63
