Question

What does e = m="latex-formula"> mean?

Answer 1

Hello again!

e = mc² is an equation that was discovered by the twentieth-century physical scientist Albert Einstein, in which E represents the  units of energy, m represents the units of mass, and c² is the speed of light squared, or multiplied by itself.

I'm not sure what it's used for, but that's what it means

I hope this helps, and have a nice day!

Answer 2

energy equals mass times the speed of light in a vacuum squared
