Expanded Notation of 525 = (5 x 102) + (2 x 101) + (5 x 100).
10 + 0.01 + 0.005
It's probably in base ten because we use base ten for all our OTHER work in numbers as well. We learn to write numbers in base ten when in elementary school, and use base ten throughout our lives even if we aren't scientists or mathematicians or students or professionals who need to use scientific notation. So keeping scientific notation in base ten makes it easier for everyone to learn and read.
Expanded Notation of 1,294 = (1 x 1,000) + (2 x 100) + (9 x 10) + (4 x 1)
