Evaluate the Limit

Problem

(lim_x→36)((√(,x)−6)/(x−36))

Solution

1. Identify the indeterminate form by substituting x=36 into the expression, which results in (√(,36)−6)/(36−36)=0/0

2. Factor the denominator using the difference of squares formula, a2−b2=(a−b)*(a+b) where x=(√(,x))2 and 36=6

3. Rewrite the expression with the factored denominator.

(√(,x)−6)/((√(,x)−6)*(√(,x)+6))

4. Simplify the expression by canceling the common factor (√(,x)−6) from the numerator and the denominator, provided x≠36

1/(√(,x)+6)

5. Evaluate the limit by substituting x=36 into the simplified expression.

1/(√(,36)+6)

6. Calculate the final numerical value.

1/(6+6)=1/12

Final Answer

(lim_x→36)((√(,x)−6)/(x−36))=1/12
