If (R) is symmetric and (R^2=R\circ R), which statement about (R^2) is correct?

Answer and explanation

Correct answer: (R^2) will always be symmetric

Step 1: Since (R) is symmetric, (R^{-1}=R). Step 2: ((R\circ R)^{-1}=R^{-1}\circ R^{-1}=R\circ R), so (R^2) equals its inverse. Step 3: For powers of relations, the inverse relation rule is very useful.
