i need help! my last math question cant figure out! whats the rule for input 3 output 9 input 4 output 16 input blank output 25 input 6 output blank input 10 output 100, thank you been stuck for over 30 minutes!!!!

Answer 1

3 >> 9
4 >> 16
__>> 25
6 >> ___
10 >> 100

The outputs sure look like squares of the inputs.

Answer 2

The answer would be x times x so..
3•3=9
4•4=16
5•5=25
6•6=36
10•10=100

The input is almost always x
The output is almost always y
So y= x•x
