The expression mRn, where m and n are positive integers, denotes that m=n[sup]2[/sup]-1, if rRs and sRp, then in terms of in terms of p, r equals
Ans: (p[sup]2[/sup]-1)[sup]2[/sup]-1

題目也看不懂,請幫我解一下,謝謝

mRn表示：m=n[sup]2[/sup]-1, 若 rRs且sRp, 求r以p表示為何？
A: r=s[sup]2[/sup]-1, s=p[sup]2[/sup]-1, 所以r=(p[sup]2[/sup]-1)[sup]2[/sup]-1
