Morphology
The meaning is directly compositional: 'square' (raise to the second power) modifies 'root' (a value solving an equation), yielding the number which, when squared, gives the original. This is a standard mathematical formation found across languages and taught early, so a B1 learner who knows the constituent senses will readily infer the MWE meaning.
Etymology
Square root comes from the idea of a square: the root is the length of its side, and when you multiply that side by itself you get the square's area. So, a square root today is the number you multiply by itself to get the original number.
