If x _ i 0, y _ i 0( i =1,2,3 n) are the values of two variable X and Y with geometric mean P and Q respectively, then the geometric mean of X Y is

Options

  1. AP Q
  2. Bantilog ( P Q )
  3. Cn ( P - Q )
  4. Dn ( P + Q )

Correct answer

B. antilog ( P Q )

Step-by-step solution

aligned & (x₁ x₂ x_n )^ 1 / n = P & (y₁ y₂ y_n )^ 1 / n = Q & ( x₁ x₂ x_n y₁ y₂ y_n )^ 1 / n = (x₁ x₂ x_n )^ 1 / n (y₁ y₂ y_n )^ 1 / n = P Q aligned
