First note that x = Floor(x) + {x}, where {} is the remainder. So if x= 2.74, then the floor is 2 + the remainder is .74 . f(x)= { 0 if x its a perfect square (like 1,4,9,...) { Floor (1/ {sqrt(x)}) otherwise So for the otherwise part, say x=2, you have 1/the remainder of sqrt(2), which is 1/.414 = 2.4

A bit string is a string of bits (0â??s and 1â??s). The length of a bit string is the number of bits in the string. An example, of a bit string of length four is 0010. An example, of a bit string of length five is 11010. Use the Rule of Products to determine the following: (a) How many bit strings are there of length eig
