-$\sqrt{(z-2)^{2}}$
A) $\mathrm{z}-2$
B) $\sqrt{\mathrm{z}}-2$
C) $(\mathrm{z}-2)^{2}$
D) $\mathrm{z}-\sqrt{2}$

Question

Quizplus · Accepted Answer

The expression $\sqrt{(z-2)^{2}}$ simplifies to $|z-2|$, which represents the positive square root of $(z-2)^2$. However, since we assume radicands do not represent the square of a negative number, and the question format implies a simplification without absolute value consideration, the closest answer is $z-2$, assuming $z \geq 2$.
