If the solution of equation LNX + 2x = 0 is x0, then the largest integer solution of inequality x ≤ x0 is

If the solution of equation LNX + 2x = 0 is x0, then the largest integer solution of inequality x ≤ x0 is


Let f (x) = LNX + 2x
f(1/3)=ln1/3+2/30
1/2



Let x0 be the root of the equation LNX + x = 4, and x0 ∈ (k, K + 1), then K is an integer=______ .


Let f (x) = LNX + x-4, then let x0 be the root of the equation LNX + x = 4, then let x0 be the zero point of F (x) = LNX + x-4. Then let f (2) = ln2-2 < 0, f (3) = ln3-1 > lne-1 = 0, then let f (2) f (3) < 0, so x0 ∈ (2, 3), х k = 2, so the answer is 2
