Evaluate 90 divided by X to the second power + y

 =34

=3⋅3⋅3⋅3

=81

For example, 3 to the power of -4:

=3−4

=134

=13⋅3⋅3⋅3

=181

=0.012346

Step-by-step explanation: the solution is expanded when the base x and exponent n are small enough to fit on the screen. Generally, this feature is available when base x is a positive or negative single digit integer raised to the power of a positive or negative single digit integer. Also, when base x is a positive or negative two digit integer raised to the power of a positive or

negative single digit integer less than 7 and greater than -7.

hopefully this is right :/
