Question

Solve for k J=k24
(a)k=±2J√J
(b)k=±4J√
(c)±4J
(d)k=±2J√

Answer 1

Here are a bunch of CORRECT answers. Your answer is in the second pic. I got number 3 wrong, but it still showed the correct answer.

Answer 2

`k=2√(J)`

Explanation:

If the equation is
`J = (k^2)/(4)`, begin by taking the square root of each side.

`√(J) = \sqrt{(k^2)/(4)} \\√(J)=\frac {k}{2}`

Now multiply each side by 2.

`√(J)=\frac {k}{2}\\2√(J) = k`

The solution is
`k=2√(J)` or option d.
