Morphology
A B1 learner who knows 'second' as indicating two and 'power' as an exponent/operation will readily infer that 'second power' means raising a number to the power of two (the square). This is a straightforward, compositional mathematical term following common cross-linguistic naming conventions, so the meaning is directly derivable from the constituents.
Etymology
The term second power comes from the simple idea of using a number twice — multiplying a number by itself. The word second shows the repeated use and power means 'raise', so a square with side 3 has area 3 × 3 and second power means 'the square' of a number.
