Question 4 of 10 Which of the following are valid names for the given triangle? Check all that
apply.
M
X
A
Α. ΔΧΜΑ
Β. ΔTAX
C. ΔΑΧΜ
D. ΔΑΧΤ
Ε. ΔTAY
Ε. ΔΧΤΑ

B,D,E

Step-by-step explanation:

A triangle can be called by their angle measures or vertices. NOT side lengths so any answer with M or Y in it is wrong.

B is right,

D is right

E is right

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)
