Q. Find the limit. limx→∞(lnx)x2A) 1B) 0C) 2D) e2
Recognize and Simplify Exponent: Recognize the form of the limit and simplify the exponent. limx→∞(lnx)x2 can be rewritten using the property of exponents as eln((lnx)x2).
Further Simplify Exponent: Simplify the exponent further.ln((lnx)x2)=x2⋅ln(lnx).
Behavior of ln(lnx): Analyze the behavior of ln(lnx) as x approaches infinity.ln(lnx) increases as x increases, but at a slower rate than lnx.
Limit Analysis: Consider the limit of (x2)⋅ln(lnx) as x approaches infinity. Since ln(lnx) grows slower than lnx and x2 approaches 0, the product (x2)⋅ln(lnx) approaches 0.
Apply Exponential Limit: Apply the limit to the exponential function.limx→∞e(x2⋅ln(lnx))=e0=1.
