Answer: 8 i

Step-by-step explanation: The square root of negative 64 is 8 i. Whenever you are finding a negative square root you need to find what times what will equal that number. 8 x 8 = 64. So the square root is 8. But, since we are finding a negative square root, the answer will be 8 i. i states that 8 is the negative square root of 64.

So the answer is 8 i.

Always add i after the number when finding negative square roots.

Answer:

1)  f=−8/7 2) z=−3/7

Step-by-step explanation:

1)-f+8=-8f

−f+8=−8f

Step 1: Add 8f to both sides.

−f+8+8f=−8f+8f

7f+8=0

Step 2: Subtract 8 from both sides.

7f+8−8=0−8

7f=−8

Step 3: Divide both sides by 7.

7f/7=−8/7

f=-8/7

2) 6z-5=-z-8

6z−5=−z−8

Step 1: Add z to both sides.

6z−5+z=−z−8+z

7z−5=−8

Step 2: Add 5 to both sides.

7z−5+5=−8+5

7z=−3

Step 3: Divide both sides by 7.

7z/7=−3/7

How do you solve 32 - 6x = 53?
katrin2010 [14]

\large\boxed{x=-\frac{7}{2}}

To solve for x, we need to isolate it on one side of the equation.

The most important part of this is knowing that whatever we do to one side of the equation, we must also do to the other.

Subtract 32 from both sides of the equation.

\begin{aligned}32-32-6x&=53-32\\-6x&=21\end{aligned}

Divide both sides of the equation by -6.

\begin{aligned}\frac{-6x}{-6}&=\frac{21}{-6}\\x&=\boxed{-\frac{7}{2}}\end{aligned}
