Answer:
$9$
Step-by-step explanation:
Given: Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again such that the calculator displays final number as $243$.
To find: number that Thea originally entered
Solution:
The final number is $243$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $243$ must be $324$.
As previously the number was squared, so the number before $324$ must be $18$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $18$ must be $81$
As previously the number was squared, so the number before $81$ must be $9$.

Therefore x(x+1)≤0, and if two numbers multiply to a negative number, one of them has to be negative and the other has to be positive. In this case, because x+1>x, x≤0, and x+1≥0
Therefore -1≤x≤0, and x can take up the value of any real number in the interval [-1,0]
Given that ΔLMN and ΔPQR are congruent triangles, therefore the corresponding parts are:
<h3>What are Congruent Triangles?</h3>
Congruent triangles has three pairs of congruent sides and three pairs of congruent angles that corresponds to each other.
Thus, given that, ΔLMN ≅ ΔPQR:
- LM ≅ PQ
- QR ≅ MN
- LN ≅ PR
- ∠L ≅ ∠P
- ∠M ≅ ∠Q
- ∠N ≅ ∠R
Therefore, given that ΔLMN and ΔPQR are congruent triangles, therefore the corresponding parts are:
