Here is how I got 48.
2^51 = 2^m * 3^3
3^3 ~ 2^5 - 2^2
therefore, 3^3~2^5
51 = m+5
m= 46
Since only option given in the answer choices is 48 which is closest to the answer that I got.
I checked with scientific calculator that 46 was the closest one.
Thats why I asked if 48 was the answer, but when the poster replied, i was perturbed to notice that it was in fact a MEMORY question.
Hope this clear your doubts.

I came to the same conclusion as Morgoth. The question is from one of the Kaplan exams (CAT tests). The answer choices were wrong to begin with.
Thanks for attempting the question. I wanted to be sure I was missing something.
