What is the <strong>MINIMUM</strong> value of p for which \frac{1}{532900}+\frac{p^{2}}{266450}+\frac{p^{4}}{523900} is an integer?
- A. 729
- B. 243
- C. 27 ✓
- D. 1
Correct Answer: C. 27
Explanation
Assuming the third denominator is a typo for 532900, the expression simplifies to \frac{1 + 2p^2 + p^4}{532900} = \frac{(p^2+1)^2}{730^2}. For this to be an integer, p^2+1 must be a multiple of 730. Therefore, p^2 = 729, which means p=27.
