If (r) is prime and (\sqrt{r}=\frac{p}{q}) is assumed in lowest form, which equation is obtained after squaring?

Answer and explanation

Correct answer: (p^2=rq^2)

Step 1: Squaring (\sqrt{r}=\frac{p}{q}) gives (r=\frac{p^2}{q^2}). Step 2: Multiplying both sides by (q^2) gives (p^2=rq^2). Step 3: This general equation applies to (2,3,5).
