The number 1953125 is equal to 5^9. explain how the information above informs you that 1953125 is not a square number
ValentinkaMS [17]

If 1953125 is a square number, then 1953125=n^2,~n\in\mathbb{N}

By what's given, 1953125=5^9\Rightarrow n^2=5^9\Rightarrow n=5^{4.5}=625\sqrt{5}

But n=625\sqrt{5} \notin\mathbb{N}, therefore, our assumption that 1953125 is a square number is wrong.

<h3>Answer: Perpendicular</h3>

The slopes -2/3 and 3/2 multiply to -1, which is sufficient info that the lines are perpendicular. Perpendicular slopes always multiply to -1 assuming neither line is vertical nor horizontal.

Note how -2/3 is the negative reciprocal of 3/2, and vice versa.
