However, if you're breastfeeding exclusively (and that means frequently, day and night), if your baby is younger than 6 months and if your period hasn't resumed, the so-called lactation amenorrhea method can be 98 percent effective in preventing pregnancy.
Then x has a expansion of decimal which terminates. 3) Let x =p/q be a rational number, such that the prime factorization of q is not of the form 25, where n, m are non-negative integers. Then, x has a expansion of decimal which is non-terminating repeating (recurring).
The decimal numbering system uses the digits 0 through 9 and the exponential powers of 10 to express a number. For example, the decimal number 207 is the sum of 2x102 + 0x101 + 7x100. The binary numbering system uses the digits 1 and 0 and the exponential powers of 2 to express a number.
