The sum of two positive numbers is 36 and their product is 180. The positive difference between them is:
24
Let the numbers be x and y, with \(x+y=36\) and \(xy=180\).
Their difference satisfies \((x-y)^2 = (x+y)^2 - 4xy = 36^2 - 4\times180 = 1296-720=576\).
So \(x-y = \sqrt{576} = 24\).
Hence, the positive difference between the numbers is 24.
Simplify: $3((\frac{5}{3})x^2 - 28x + 15) - 5(x^2 + 6x - 15)$
If m + n = 24, then (m - 16)³ + (n - 8)³ is ____.
For the following equations, what are the values of a and b to have infinitely many solutions?
ax + by = 2
3x - (5 - 2ay) = 6
If \(x + \frac{1}{x} = 2\), then the value of \(x^{99} + \frac{1}{ x^{99} } - 2\)
If \(2x - \frac{1}{2x} = 5\), \(x \neq 0\) then the value of \(x^{2} + \frac{1}{16x^{2} } - 2\) is
