We are asked to solve the equation n+⌊n⌋+⌊3n⌋=2014 for positive real numbers n.
To begin, we denote:
- x=⌊n⌋,
- y=⌊3n⌋.
Thus, we have:
x≤n<x+1
y≤3n<y+1
Therefore,
x2≤n<(x+1)2
y3≤n<(y+1)3
Substituting these into the original equation, we have:
n+x+y=2014
Next, we will approximate values to find the range for n.
1. **Approximate n and 3n**
Since x=⌊n⌋ and y=⌊3n⌋, assume that:
n≈x2andn≈y3
2. **Estimate n:**
From the equation, n+x+y=2014, express x and y in terms of n:
x≈nandy≈3n
Substituting:
n+n+3n≈2014
Let's try some approximate calculations:
3. **Trial Calculation for n:**
Suppose n=1958, then:
1958≈44.23⇒⌊1958⌋=44
31958≈12.57⇒⌊31958⌋=12
Hence,
1958+44+12=2014
This satisfies the equation.
Thus, the solution to the equation in positive real numbers is:
1958
