The difficulty of the task does not depend on the number of digits of the perfect power but on the precision, i.e. the number of digits of the root . In addition, it also depends on the order of the root; finding perfect roots, where the order of the root is coprime with 10 are somewhat easier since the digits are scrambled in consistent ways, as we shall see in the next section . </P> <P> An easy task for the beginner is extracting cube roots from the cubes of 2 digit numbers . For example, given 74088, determine what two digit number, when multiplied by itself once and then multiplied by the number again, yields 74088 . One who knows the method will quickly know the answer is 42, as 42 = 74088 . </P>
