RE: (sqrt(2))^2
https://en.wikipedia.org/wiki/Order_of_operations says
The root symbol, √, requires a symbol of grouping around the radicand. The usual symbol of grouping is a bar (called vinculum) ̄ ̄ over the radicand √ ̄ ̄. Other functions use parentheses around () the input to avoid ambiguity. https://en.wikipedia.org/wiki/Vinculum_(symbol) sorry google translator > on 2D template of √ included the symbol ̄ ̄ that distinguishes or group the expression of radicand, in 1D the only way of grouping expression of the radicand is to use Bracket https://en.wikipedia.org/wiki/Bracket_(mathematics) √( ), parentheses √[ ] square brackets √{ } braces √<> angle brackets This is the convention that follow several CAS I've tried √[2]^2 == √(2)^2 == SQRT(2)^2 = 2 and not SQRT(2^2) another symbol to delimit can be ¬ √ ¬ √2¬^2 I suggest that in Algebraic mode (1D) pressing √ key, the parentheses is incorporated on entry line [√] > √()
