Round the following number to the nearest hundred

123,456

Hey!

Your answer is 123,500!

Step-by-step explanation:

TO ROUND TO THE NEAREST HUNDRED we need to look at the TENS column...

IN THIS CASE WE LOOK AT '5'...

If its bigger than 4 INCREASE THE DIGIT IN THE HUNDREDS PLACE BY ONE

If its smaller than 5 DECREASE THE DIGIT IN THE HUNDREDS PLACE BY ONE!

So as 5 is a digit that makes us ROUND UP...we change 4 to a 5 to have 123,500 as our answer!

HOPE THIS HELPS!

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)
