How do you figure out the square root of z^2+8z+16?

Step-by-step explanation:

Hey there!

Given;

Looking through question, we can bring it to perfect square to remove the (√) sqrt.

We made this to bring it in the form of (a+b)^2. As (a+b)^2 = a^2 + 2.a.b + b^2.

Now, our question looks like similar to the formula.

So, We can write it as:

Now, we can cancel (√) and (^2). And we get

= z + 4

Hope it helps...

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
