Question

If e^2=e^(4x+7) then does 2=4x+7? If so...why? - Is it 'by the nature of equality'? I've heard this but I don't know what it means :) Thanks

Answer 1

so for example

a^x =a^y

than you see that the base (in this case a ) are the same in right side like in left side so than just you need make equale the exponents so in this case x=y

hope you understand it

Answer 2

Ok thanks :)

Answer 3

was my pleasure

good luck
