For some reason, my explination isn't formatting properly, hope this helped

Step-by-step explanation:

The angle is 60 degrees so the triangle is half of an equilateral triangle

so y is half of the hypotenuse:

y = 16/2 = 8

x = √16^2 - 8^2 = √256 - 64 = √192  = 8√3

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)
