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...

yes

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
