Simplify $\sqrt{50}$ to simplest radical form.

Which one-line statement best describes the Square Root Property?

A robotic arm's displacement from a reference point at time $t$ minutes satisfies $(t-2{)}^2=5$. Solve for $t$ and state which solutions are physically meaningful.

Solve $(2x+3{)}^2=50$ and simplify the answers.

Solve $x^2=-25$ and express the solutions in standard complex form.
