Evaluate the expression
for x = 3.
72
2

Start by plugging in 3 as x. Next square the given values both on the top and bottom. It gives us 49/9-2. 49/7. ( explanation:for the top if we square 7 we get 49. For the bottom if we square 3 we get 9 and there’s also a 2 that we should subtract. We get 7 on the bottom. 49/7. Here we divide 49 by 7 and as a final result we get 7. Hope I was able to help.
