Lizzie came up with a divisibility test for a certain number : m not equal to 1 Break a positive integer n into two-digit chunks, starting from the ones place. (For example, the number 354764 would break into the two-digit chunks 64,47,35)

Find the alternating sum of these two-digit numbers, by adding the first number, subtracting the second, adding the third, and so on. (In our example, this alternating sum would be 64-47+35=52)

Find m and show that this is indeed a divisibility test for m (by showing that n is divisible by m if and only if the result of this process is divisible by m).

3/40 or 0.075

Step-by-step explanation:

Given:  log   fourth root of 3

                  b

... we can write the equivalent:

log   fourth root of 3 = (1/4)*log  3    (1/4)*(0.3) = 3/40 or 0.075

     b                                           b
