.78=2(3.14)*sqrt.5/g

solve for g

.78 = 2π(1/√2)/g

.78 = π√2/g
g = π√2/.78 = 5.69

To solve for the variable g in the equation .78 = 2(3.14) * sqrt(5) / g, we can follow these steps:

Step 1: Move the variable g to the other side of the equation.
To do this, we can multiply both sides of the equation by g to cancel out the denominator:

.78 * g = 2(3.14) * sqrt(5)

Step 2: Simplify the equation on the right side.
Compute the value of 2(3.14) * sqrt(5):

2(3.14) * sqrt(5) ≈ 9.8969

Step 3: Isolate the variable g.
Divide both sides of the equation by .78 to solve for g:

(.78 * g) / .78 = 9.8969 / .78

This simplifies to:

g ≈ 12.676

Therefore, the approximate value of g in the given equation is 12.676.
