What is the prime numbers from 200 to 300

Step-by-step explanation:

We create a table of all numbers from 200 to 300.

Look at the picture (#1).

We cross out all even numbers (#2).

We find the first number divisible by 3 (201) and cross out every third number (#3).

We continue this way (numbers divisible by 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41,...).

In your task, it is enough until 17.

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)
