Solving for f in the Equation d = 16ef^2

Understanding the Given Equation

The given equation is d = 16ef^2, where d, e, and f are variables. To solve for f, we need to isolate f on one side of the equation. This involves using algebraic manipulations to simplify the equation and express f in terms of the other variables.

Option A: f = ± 4√(d/e)

Let's start by examining option A: f = ± 4√(d/e). To verify this option, we can substitute the expression for f into the original equation and see if it holds true.

First, we can rewrite the expression for f as f = ± 4√(d/e) = ± 4√(d) / √(e).

Now, substitute this expression for f into the original equation:

d = 16e(± 4√(d) / √(e))^2

Expand the squared term:

d = 16e(± 16d / e)

Simplify the expression:

d = ± 256d

This equation is not true for all values of d, so option A is not a valid solution.

Option B: f = ± 4√(de) / e

Next, let's examine option B: f = ± 4√(de) / e. We can substitute this expression for f into the original equation and see if it holds true.

First, we can rewrite the expression for f as f = ± 4√(de) / e = ± 4√(d) / √(e).

Now, substitute this expression for f into the original equation:

d = 16e(± 4√(d) / √(e))^2

Expand the squared term:

d = 16e(± 16d / e)

Simplify the expression:

d = ± 256d

This equation is not true for all values of d, so option B is not a valid solution.

Option C: f = ± √(d/16e)

Finally, let's examine option C: f = ± √(d/16e). We can substitute this expression for f into the original equation and see if it holds true.

First, we can rewrite the expression for f as f = ± √(d/16e) = ± √(d) / √(16e).

Now, substitute this expression for f into the original equation:

d = 16e(± √(d) / √(16e))^2

Expand the squared term:

d = 16e(± d / 16e)

Simplify the expression:

d = ± d

This equation is true for all values of d, so option C is a valid solution.

Conclusion

In conclusion, the correct solution for f in the equation d = 16ef^2 is f = ± √(d/16e). This solution is verified by substituting the expression for f into the original equation and simplifying the resulting expression.
