\[\sum_{x=99}^∞\sum_{y=88}^∞\sum_{z=110}^∞\sum_{g=999}^∞ 100\frac{e^{10}(x^{3}+y^{3} \times z^{3})}{\prod_{n=1881}^∞\frac{n^{5}}{100}+\sqrt{g}}\]

if the above equation is equal to \[\frac{a}{b}\] find \[a \times b\] then minus that number by 1/2

i wont post solution until you do

Oh meee gord sooo deeffirricalt. Though honestly, this sum doesn't make any sense. One look and you'll know it doesn't even converge. – Julian Poon · 11 months, 2 weeks ago

But converging isn't involved, and you'll see whyLog in to reply

Ok, I think you just have a misconception of how the summation works. Go look up on it to see how you can rephrase your question. I've also noticed you changed the question. It still doesn't converge.Log in to reply

Kindly refrain from using note titles like you did previously. These may provoke fights which are uncharacteristic to the Brilliant community. – Mehul Arora · 11 months, 2 weeks ago
