Question

√(x + 20) = √256 – √169
y² + 256 = 377

  • A) X > Y
  • B) X < Y
  • C) X ≥ Y
  • D) X ≤ Y
  • E) X = Y or relation cannot be established
Solution

D. X ≤ Y
Explanation:
√(x + 20) = √256 – √169
x + 20 = 9 => x = -11
y² + 256 = 377
y = ± 11

D. X ≤ Y
Explanation:
√(x + 20) = √256 – √169
x + 20 = 9 => x = -11
y² + 256 = 377
y = ± 11
