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
