9-16. Paul built a tower by stacking six identical layers of the shape at right on top of each other.
a. What is the volume of his tower? How can you tell without building the shape?
b. What is the surface area of his tower?
c. Paul's tower is an example of a prism because it is a solid and two of its faces (called bases) are congruent and parallel. A
prism must also have sides that connect the bases (called lateral faces). Each lateral face must be a parallelogram (and thus
may also be a rectangle, rhombus or a square).
For each of the prisms below, find the volume and surface area.

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)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
