How many 0's are located to the right of the decimal point and before the first non-zero digit in the terminating decimal representation of

2⁵ / 5⁸  =   (2/5)⁵ * (1/5)³ = (4/10)⁵ * (2/10)³ = [4⁵ * 2⁴] / [10⁸] = 16384/10⁸ ......and the  number of leading zeroes will equal [the number of zeroes in the denominator - the number of digits in the numerator] = [8 - 5] = 3 leading zeroes
