Let the numbers be x and y
xy = 24
x^2 + y^2 = 52
So
(x+y)^2 = x^2 + y^2 + 2xy
(x+y)^2 = 52 + 48
(x+y)^2 = 100
x + y = 10
So their sum is 10.

Step-by-step explanation:
Let the two numbers be x and y.
As per question,
x X y = 24
x = 24 / y
x² + y² = 54
(24/y)² + y² = 54
576 / y² + y² = 54
576 + y^4 = 54 y²
y^4 - 52 y^2 + 576 = 0
y^2 = 52 + 20 / 2 = 36
y = 6
Now,
x = 24/6 = 4
Hence, sum of the two numbers = 6 + 4 = 10
Hope it helps.
