Hello, all--(adsbygoogle = window.adsbygoogle || []).push({});

I have the following series that I'm supposed to calculate:

[tex]\sum_{i=1}^{\infty} \sum_{j=i}^{\infty} p^(j+i)[/tex]

Could someone show me how it should be done?

Note: It's supposed to be p^(j+i) or p raised to j+i; however, I can't get the formatting to work.

Anthony
