HELP!!!

28  x  98 ==2,744

2,744^(1/3) ==14

So, your 2-digit number is: 98

Let the answer number be y

the 2 digit number be M

$10\le M\le99\\ 280\le 28M\le 2772\\ 280\le y^3 \le 2772\\ 7\le y \le 14\\ $

So y could be  7, 8, 9, 10, 11, 12, 13, or 14

7^3 = 343   and 343 is not divisable by 28 so the answer is not 7

Just try all the other numbers to find the one that works.   

28 = 2^2 * 7

So, the smallest 2-digit number will be:

2^1 x 7^2 ==98

So, the perfect cube will be:

2^3 x 7^3 =2,744
