$\frac{3^3+3-30}{3^3-3-18}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(3)lim((x^3+x+-30)/(x^3-x+-18)). Evaluate the limit \lim_{x\to3}\left(\frac{x^3+x-30}{x^3-x-18}\right) by replacing all occurrences of x by 3. Subtract the values -3 and -18. Subtract the values 3 and -30. Calculate the power 3^3.
