Motivated by recently developed interest to the distribution of -ary digits of Mersenne numbers , where is prime, we estimate rational exponential sums with , , modulo a large power of a fixed odd prime . In turn this immediately implies the normality of strings of -ary digits amongst about rightmost digits of , . Previous results imply this only for about rightmost digits.
