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

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

So therefore, we can definitely say that 𝑎 squared is 𝑎 multiplied by 𝑎. And that’s the third answer.
