In a certain code language, POST is written as 5927 and

I. y² - 7 y – 18 = 0

II. x² + 10 x + 16 = 0

I. y/16 = 4/y 

II. x³ = (2 ÷ 50) × (2500 ÷ 50) × 4² × (192 ÷ 12)

I. x² – 18x + 81 = 0

II. y² – 3y - 28 = 0

What will be the product of smaller roots of both equations. 

Solve the quadratic equations and determine the relation between x and y:

Equation 1: 21x² - 82x + 80 = 0

Equation 2: 23y² - 132y + 85 = 0

I. x + 1 = ³√ 9261

II. y + 1 = √ 324

I. 2y² - 35y + 132 = 0

II. 2x² - 31x + 110 = 0

I. 2x² - 15x + 27 = 0

II. 2y² - 13y + 20 = 0

I: 3x² - 18x + 24 = 0

II: 5y² + 10y - 15 = 0

I. x² – 13x + 36 = 0

II. 3y² – 29y + 18 = 0
