e=square root d/ab,make d the subject

or, as we say in English, "solve for d"

e = √d/ab
eab = √d
(eab)^2 = d

if you were careless with parentheses, and meant

e = √(d/ab)
e^2 = d/ab
abe^2 = d

To make "d" the subject of the equation e = √(d/ab), we need to isolate it on one side of the equation. Here's how you can do that step-by-step:

1. Start with the equation e = √(d/ab).

2. Square both sides of the equation to eliminate the square root: (e^2) = (√(d/ab))^2.

3. Square root and square cancel each other out, leaving us with: (e^2) = (d/ab).

4. Multiply both sides of the equation by ab to get rid of the denominator: (ab)(e^2) = d.

5. Finally, we can rewrite it as: d = (ab)(e^2).

Thus, the equation d = (ab)(e^2) represents "d" as the subject.
