To divide the given expressions, we can simplify the numerators and denominators separately and then divide.
Simplifying the numerator:
√39 = √(3 * 13) = √3 * √13 = √3√13 = √(3 * 13) = √39
Simplifying the denominator:
√13 = √(13)
Now, we can rewrite the expression as:
(36√39)/(9√13) = (36 * √39)/(9 * √13)
Canceling out common factors:
= (4 * 9 * √3 * √13)/(9 * √13)
Now, we can cancel out the common factor of 9 and √13:
= (4 * √3)
The exact answer is 4√3.
