Answer 2

Hey there!

ANSWER: $c=2 \text{ or } c=-2$

EXPLANATION:

$c^2=4$

If you are looking to find c, let's see what types 2 equals for.

$c*2=4$

We know a number * 2 = 4. That number is 2. Let's see if c is equal to 2.

$c*2=4\\2*2=4$

The answer is true because 2 * 2 does equal 4. So the answer is $c=2$.

$c=2$

But the value can be a negative as well because $2^2$ is also equal to 4.

$c^2=4\\-2^2=4\\c=-2$

Hope this helps!
