If h(x)=6-x, what is the value of (h•h)(10)?
a. -4
b. -2
c. 10
d. 16

For this case we have the following function:

We want to find the value of:

We have then:

Evaluating the function for x = 10 we have:

Then, replacing values we have:

the value of (h • h) (10) is:

Option D.

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)
