i think everyone is familiar to this but i wonder if someone has made his research to study it.(adsbygoogle = window.adsbygoogle || []).push({});

what i mean is the namubers that when the result of multiplying them together is the same as adding them:

for example:

2*2=2+2=4 (trivial, i know (-: ).

3*1.5=3+1.5=4.5

my question has someone prooved that the number of these pairs are finite or infinite in the real numbers?
