38. writing in math explain why the rules for the order of operations ar
important. support your answer with two numerical examples.

Order of operations is important because you need to go in order to get the correct answer

Step-by-step explanation:

Ex: 3+5-5 x 10

You would first do your multiplication and 5 x 10 = 50.

Next you would proceed to 3 + 5 to get 8. Then you would do 8 - 50 to get 42

Next is:

10-2/2

You would do 2/2 first to get 1 and 10 - 1 is 9. If you did 10 - 2 you would have gotten 8 and 8/2 equals 4 and not 9

3/6   and 9/18

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)
