Here are two closed containers and four balls just fit in each container. 0000 foto
Curved surface area
of a cylinder is 2īrh
Container A
Container B
Each ball has a diameter of 60 mm.
Which container has the smaller surface area?
You must show your working (using mm).
Your final line should say either, 'A is smaller' or 'B is smaller'.

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)
