Step-by-step explanation:

Given:

E is the midpoint of segment AC.

AE ≅ EC

∠BAE ≅ ∠ECD

To prove:

ΔAEB ≅ ΔCED

                    Statements                          Reasons

1). AE ≅ EC                                          1). Given

2). ∠BAE ≅ ∠ECD                              2). Given

3). ∠AEB ≅ ∠CED                              3). Vertically opposite angles theorem

4). ΔAEB ≅ ΔCED                              4). By ASA postulate of congruence

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
