Well

Points for originality, though this appears to be a mathematically/technically incorrect representation of 10 Years of B.

But really, it could do with something more, you're not the only one that did a 0.# KB flash with B and 10 in it for Clock Day.

Technicality

Celebrating 10 years of be would be expressed mathematically as 10B, as years are measured as numbers with a constant linear progression. Years as we measure them do not increase exponentially. In other words, according to your equation, time would move at an exponential rate, and as big as B is, time would actually move much faster in Clocktopia than we perceive it to move in our world.

Damn, that B is powerful.
