y = p x q^(x - 1), When x = 1, y = 10, and when x = 6, y = 0.3125. Find the value of 'y' when x = 3

When x = 1, y = 10Therefore, p x q (1 - 1) = 10 p x q 0 = 10 p x 1 = 10, p = 10When x = 6, y = 0.3125 p x q (6 - 1) = 0.3125 10 x q 5 = 0.3125 q 5 = 0.03125, q = (0.03125) 1/5 , q = 0.5Let x = 3, 10 x 0.5 (3...
