Length of positive integer n is defined by multiplying its prime factors. eg: l of 75 is 3.

3*5*5.

How many 2 digit ints have length 6?

(I thought to pick the smallest prime no. to give max. length - something i learned from OG!)

2^6 = 64
but 3^6 is a 3 digit no.

so How is the answer 2?

Your approach is right. Just try to replace one 2 with 3, still it is a 2 digit int.
