Find x, given 5 (√5)^x+6 = (√5)^2x+7 :

If x² + y² + 2x + 1 = 0, therefore the value of x³¹ + y³⁵ is

If -5 ≤ x ≤ 3 and -1 ≤ y ≤ 0, then the minimum value of 2y – 3x is:

Quantity I – ³

Quantity II – 25⁴

If > 0 and < 0

 is equal to:

If the nine-digit number 43x1145y2 is divisible by 88, then the value of (3x — 2y), for the smallest value of y, is:

If 2cos² Ɵ – 5cos Ɵ + 2 = 0,0⁰ < Ɵ < 90⁰ , then the value of (cosec Ɵ + cot Ɵ) is :

The total number of even factors of 2⁵ × 3³ × 5² is:

If x sin³ θ + y cos³ θ = sin θ cos θ and x sin θ − y cos θ = 0, then the value of x² + y² equals
