Assignment:Find the solution set of inequality ((35-3.289*(4.1077+lnx)-10-0.051*(3.289/x-0.1))*2*3.14*20*6.996*10^(-7)*8.64*10^4)/3.4904285-lnx >10 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( ( 35 - 3.289 * ( 4.1077 + ln x ) - 10 - 0.051 * ( 3.289 / x - 0.1 ) ) * 2 * 3.14 * 20 * 6.996 * 10 ^ ( -7 ) * 8.64 * 10 ^ 4 ) / 3.4904285 - ln x >10 (1)
From the definition field of ln
x > 0 (2 )
From the definition field of divisor
x ≠ 0 (3 )
From the definition field of ln
x > 0 (4 )
From inequality(1):
The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
From inequality(2):
x > 0
From inequality(3):
x < 0 或 x > 0
From inequality(4):
x > 0
The final solution set is :
The solution set is empty,that is, the inequality will never be estatlished within the real number range.
