Sample Solved JEE Main Question
Here is an example problem from the practice sets[cite: 4]:
Problem: Exponential Logarithmic Integration
Question: Evaluate $\int \frac{e^{5\log x} – e^{4\log x}}{e^{3\log x} – e^{2\log x}} dx$[cite: 4].
Step-by-Step Solution:
- Simplify Logarithmic Powers:
Using $e^{\log a^b} = a^b$, we rewrite the terms:
$e^{5\log x} = x^5$, $e^{4\log x} = x^4$, $e^{3\log x} = x^3$, $e^{2\log x} = x^2$[cite: 4]. - Rewrite Integrand:
$\int \frac{x^5 – x^4}{x^3 – x^2} dx = \int \frac{x^4(x – 1)}{x^2(x – 1)} dx$[cite: 4]. - Simplify Terms:
Canceling $(x – 1)$, we get $\int x^2 dx$[cite: 4]. - Final Integration:
$\int x^2 dx = \mathbf{\frac{x^3}{3} + C}$[cite: 4].
