2 inches is approximately 5 centimeters. Kevin is 66 inches tall. How many centimeters (cm) tall is he? Idk I'm to dumb for this

Basically, all you have to do is divide 66 by two then multiply times 5. So he is 165 centimeters tall. Hope this helps! You can also divide 5 by 2 and you still get the same answer!

Step-by-step explanation:

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)
