Step-by-step explanation:
![c^2=4](https://img.qammunity.org/2021/formulas/mathematics/high-school/b8fco08yt8ucz8dap1gsi76dg46hp632of.png)
If you are looking to find c, let's see what types 2 equals for.
![c*2=4](https://img.qammunity.org/2021/formulas/mathematics/high-school/1cbgl2g1oafphzek6g5qinp0r09geytdvs.png)
We know a number * 2 = 4. That number is 2. Let's see if c is equal to 2.
![c*2=4\\2*2=4](https://img.qammunity.org/2021/formulas/mathematics/high-school/m43h1c5xi9gjsh1vf17t52ld4azlc9te56.png)
The answer is true because 2 * 2 does equal 4. So the answer is
.

But the value can be a negative as well because
is also equal to 4.
![c^2=4\\-2^2=4\\c=-2](https://img.qammunity.org/2021/formulas/mathematics/high-school/ytg6ijcie30sk7ztrr7decptfwdntc329g.png)
Hope this helps!
