Which number is the least 0.092, 0.029, 0.043

0.029

Step-by-step explanation:

beacue there are all the same up to 0.0... so, the smallest first number is 2 therefore, 0.029.  

0.029

This is the smallest naumber because 0.092 is greater that it and so is 0.043.

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)
