Which of these can be written as π‘Ž squared? Circle your answer. The options are π‘Ž plus π‘Ž, π‘Ž minus π‘Ž, π‘Ž multiplied by π‘Ž, or π‘Ž divided by π‘Ž.

Well, we know that π‘Ž squared means π‘Ž multiplied by itself. So this is the same as π‘Ž multiplied by π‘Ž. So therefore, the correct answer is going to be the third answer, π‘Ž multiplied by π‘Ž. But let’s take a look at the other answers and see what they would’ve given us. Well, π‘Ž plus π‘Ž would be the same as one π‘Ž plus one π‘Ž, which would just be two π‘Žs. So π‘Ž plus π‘Ž would’ve been two π‘Ž. π‘Ž minus π‘Ž would be zero because anything minus itself is just going to be zero. And π‘Ž divided by π‘Ž is just going to be one. And that’s because anything divided by itself is one.

So therefore, we can definitely say that π‘Ž squared is π‘Ž multiplied by π‘Ž. And that’s the third answer.
