# Division

Given positive integers $t$, $a$, and $b$ not bigger than $2\, 147\, 483\, 647$, establish whether $(t^ a - 1)/(t^ b -1)$ is an integer with less than $100$ digits.

## Input

Each line of input contains a test case $t$, $a$ and $b$. There are at most $100$ lines of input.

## Output

For each line of input print the formula followed by its value, or followed by “is not an integer with less than $100$ digits.”, whichever is appropriate.
