Heavens knows why I've been asked to answer this one, but I obviously have a different mind...
The answer is 72 or 90, possibly others. It could be anything.
For each equation we have two numbers to deal with and we're not told how to approach the problem and we're not told actually what, if any, operation has been made on the first number.
The first number of each equation is given, the second, and the operation, we must assume, (amongst a whole lot of complicated other things, like base.)
We're given 2; 3; 4; 5; 6; 9.
We're asked to pluck from mid-air a missing element.
Should it be the next in a series: 3; 4; 5; 6; 7?
Then either '8', the next in the sequential series, or '10', the next in an assumed series that remains synced to the first number. No information about which series should be followed, if any.
9*8=72
9*10=90
All we have been given is equations; forced equivalents. Nothing is actually given to us to follow. Sticking firmly to the question, it is unanswerable, because we have not been required to assume a pattern. It is entirely possible that—if there is a pattern—it could include an operation involving my birthday and the number of clouds I can see.
I mean, two does not equal six. To declare that it does (in arithmetic) is prima fascie a nonsense. If it is a simple logical declaration, 2 could also equal double-u. Anything else could equal anything else; and in that case there doesn't have to be a pattern.
