Question

Make d the subject of the formula; n=k/d^2

Answer 1

d = √(k/n)

Explanation:

n = k/d²

n/1 = k/d²

Cross multiply.

k = nd²

Divide both sides by n.

k/n = nd²/n

k/n = d²

Take the square root on both sides.

√(k/n) = √(d²)

√(k/n) = d

Answer 2

`n = \frac{k}{ {d}^(2) }`

`{d}^(2) = (k)/(n)`

`d = \sqrt{ (k)/(n) }`

Here is the required firmula....
