High School Placement Test (HSPT) Practice Test

Which number is equivalent to 2 squared?

1. 4

2. 2

3. 8

4. 6

The correct answer is: 4

To determine which number is equivalent to 2 squared, we first need to understand what "squared" means mathematically. Squaring a number involves multiplying that number by itself. Therefore, 2 squared can be calculated as follows: 2 squared = 2 × 2 = 4. This demonstrates that the value obtained from squaring 2 is indeed 4. Additionally, looking at the other options, none of them reflect the outcome of squaring 2, which is specifically 4. The other numbers—2, 8, and 6—are all different values and do not satisfy the mathematical operation of squaring the number 2. Thus, the only correct conclusion from the problem is that 4 is the equivalent number to 2 squared.
