sqrt
Computes the principal square root of an expression.
Square roots are represented through a one-half power and simplified with Nerdamer's radical rules. Perfect squares and compatible radical products are reduced exactly.
For symbolic squares, sign information matters: without a sign assumption sqrt(x^2) simplifies to abs(x).
Examples
These examples use Nerdamer Notation.
Reduce a perfect square exactly.
sqrt(9) // → 3
Return the exact principal complex square root.
sqrt(-9) // → 3*i
Preserve the sign ambiguity of a symbolic square.
sqrt(x^2) // → abs(x)
