Answer:
3⁷ x 7³ x 11²
Just write down the product of the highest power of all the powers that appear in either or both numbers.
If "4/2/7" is all we have to work with, then PEMDAS rules will save the day. Do the division from left to right.
4/2 becomes 2. Then we have 2/7, a proper fraction. I don't see where an improper fraction would come from in this case.
24 units or you can put 7x4 units
4¹/₂ × ⁶/₁₇
⁹/₂ × ⁶/₁₇
²⁷/₁₇
1¹⁰/₁₇
The product of 4¹/₂ and ⁶/₁₇ will be smaller than 4¹/₂.
