Full solution

Q. limx75x+25x3+x+2=_____ \lim _{x \rightarrow \infty} \frac{75 x+25}{x^{3}+x+2}=\_\_\_\_\_
  1. Divide by x3x^3: To find the limit of the function as xx approaches infinity, we need to analyze the behavior of the numerator and the denominator separately. The highest power of xx in the denominator is x3x^3, so we should divide every term in the numerator and the denominator by x3x^3 to simplify the expression.
  2. Simplify the function: After dividing each term by x3x^3, the function becomes: limx75/x2+25/x31+1/x2+2/x3\lim_{x \rightarrow \infty} \frac{75/x^2 + 25/x^3}{1 + 1/x^2 + 2/x^3}
  3. Terms approach 00: As xx approaches infinity, the terms with xx in the denominator approach 00. Therefore, the function simplifies to: limx(0+0)(1+0+0)\lim_{x \rightarrow \infty} \frac{(0 + 0)}{(1 + 0 + 0)}
  4. Calculate the limit: The limit of the function as xx approaches infinity is then: 01=0\frac{0}{1} = 0
