square root 225 cube root 36.9932 fourth root 15 fifth root 8.7272. Step-by-step explanation: In mathematics extracting a root is known as the determination of the unknown "x" in the equation y=xn The outcome of the extraction of the root is declared as a so-called root. In the case of "n is 2", one talks about a square root or sometimes
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
