For some reason I keep getting it wrong I don't know if it's a calculation error. Please show your work so I can see what I'm doing wrong in this given problem:

Problem: An electron has a speed of v = 0.915 c. What is its total energy (rest energy plus kinetic energy)?

Show how you get the answer, so that I can better understand how to do it.
