What is 10,000 x 10,000

not important lol I just wanna know

100000000

Step-by-step explanation:

Basic way to do this when using 10's 100's 1000's and up, count the number of zeros on the end and multiple the first regular number then add the zeros back :D

100,000,000

Step-by-step explanation:

10,000 has 4 zeros. Double the number of zeros and you get 100,000,000, or one oh oh, oh oh oh, OH OH OOOH

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)
