structual concern

while removing a small section of dry rotted flooring I cut through some floor joists 2x10's the cuts are 1/4'' to 3/8" deep and 3 inches apart creating a notch 2.5 inches from the end of the joist. this is a cantilevered section of the house the cantilever is 36" past support wall there are 5 joists grouped together with 2 jack studs and a king stud resting on them the cuts are on the tension side of the joists is there a repair? are the cuts so shallow that I need not be concerned?

structual concern

Some others may disagree but I wouldn't worry about it, most dimensional lumber can vary more than that from one joist to another. In other words most 2X10s will very from 9 inches to 9 1/2 inches so the cuts you have made shouldn't be of any concern especially that close to the end of the joist.

structual concern

Thanks for you're response I need the reassurance that I have not destroyed my home. spoke to a engineer he agreed said that joists always have more capacity then needed and I took away 3 to 6% of there capacity

This size cuts close to the end of the cantilever are insignificant.
