Question

Pre-Calc: Perform the operation and write the result in standard form. (Simplify completely)

Answer 1

`\left( √(-27) \right)^2\implies \left(√((-1)(27)) \right)^2\implies \left( √(-1)\cdot √(27) \right)^2\implies \left( √(-1) \right)^2 \left( √(27) \right)^2 \\\\\\ i^2\cdot 27\implies -1\cdot 27\implies -27`
