For some reason, I didn't get it the answer, how 5. 3^2+3^2 .2
= 27?
Same question goes for column B
Can u please clarify the answer for me!

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

I guess there's a typo error its not 3^2 x 9 it's
3^2 x 7
3^2 x 7

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.
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.

I don't understand the answer, where did you get 64 and 27

Hi Nupcia,
3 · 2 + 7 · 3 =
6 + 21 =
27
and
5 · 3^2 + 3^2 · 2 =
5 · 9 + 9 · 2 =
45 + 18 =
63
Nova Press
3 · 2 + 7 · 3 =
6 + 21 =
27
and
5 · 3^2 + 3^2 · 2 =
5 · 9 + 9 · 2 =
45 + 18 =
63
