The probability of n heads in a row tossing a fair coin is 2−n Input The first line of the input contains an integer r. Then r lines containing each one an integer number n. Thevalueofnisasfollows: 0<r<10,0<n≤9000. Output Print r lines each with the value of 2−n for the given values of n, using the format: 2^-n = x.xxxE-y where each x is a decimal digit and each y is a decimal integer with no leading zeroes or spaces. Sample Input 8271 6000 1 Sample Output 2^-8271 = 1.517E-2490 2^-6000 = 6.607E-1807 2^-1 = 5.000E-1
