Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).
We split up the radicand into perfect squares. Once we do, we take out the things that were squared:

Answer:
Step-by-step explanation:
Converse of alternate interior angles theorem:
This theorem states that if two lines are intersected by a transversal and the alternate interior angles are congruent, lines will be parallel.
Therefore, p║n.
Perpendicular transversal theorem:
By this theorem,
In a plane, if a line is perpendicular to one of two parallel lines, then it will be perpendicular to the other line.
Therefore, l ⊥ p.

Answer:
3/10
Step-by-step explanation:
(3/8)/(1 1/4) = (3/8)/(5/4) = (3/8)/(10/8) = 3/10
