Answer 2

See explanation

Explanation:

We want to find the value of k in

`√(10k) + 3 = 5`

We subtract 3 from both sides;

`√(10k) = 5 - 3`

Simplify on the right;

`√(10k) = 2`

Square both sides;

`10k = 4`

`k = 0.4`

If your equation in actually

`√(10k + 3) = 5`

Square both sides:

`10k + 3 = 25`

`10k = 22`

`k = 2.2`
