at a summer camp 23 of the boys and 17 of the girls can swim there nine boys 11 girls at the camp who cannot swim. what is the ratio or the number of children who can swim to the number of children who cannot swim.

30 kids that can swim to 20 kids who cannot swim.

Step-by-step explanation:

There are 30 kids who can swim and 20 kids who can not swim.

So the ratio is 30  kids who can swim and 20 kids who can not swim.

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)
