Square root of 4489 by division method

Consider first two digits and then the next two digits.If there are three digits in the given number then first consider the first digit and then the take two digits together

6 | 4489 | 6x

36

12x | 889 |

Now the number 889 has 9 in units place so take a share number which has 9 at the end (ex.3*3=9 and 7*7=49)

So put 7 in the place of x and multiply the x value with 12x(that is 127) u will get the remainder as 0

Therefore the square root of 4489 is 6x*6x i.e. 67*67=4489

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)
