Sorry, but I didn't understand the explanation

Look at the answer choices carefully. They are in form of [X] not X.
You got the 81 part correct because [9]*[6] = 81

But the answer choices is NOT 81 because [81] != 81

[27] = 3*27 = 81

:wink:

I am sure a lot of people would fall for the trap under pressure. Just be careful...
