Please help with this simple question.

32° or 32 degrees

Step-by-step explanation:

Using TOA which is opposite/hypotenuse

We say that;

Tan(x) = 7/11

You do the inverse of Tan which is Tan^-1 to solve for x

Therefore Tan^-1 7/11 = 32.47119229° which is approximately 32° or 32 degrees.

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)
