Question #3d46e

Answer 1

`k = pm 5`

Explanation:

Well, `k^2+25` is just an expression, and without something on the other side of the equation, it’s impossible to solve for `k` .

However, since the “=“ and “+” keys are extremely close together on the keyboard (or just a shift key apart on the computer), I’m assuming you meant `k^2 = 25`. In which case:

Take the square root of both sides. `sqrt(k^2)=k`, just like the `sqrt(3^2)=`3. The square root of the other side, `sqrt(25)`, is `5`, so `k = 5`.

Here it is worked out:
`k^2 = 25`
`sqrt (k^2) = sqrt (25)`
`k = pm5`
