Question

what is e^x into e^x ?

Answer 1

Assuming you mean \[e ^{x}/e ^{x}\], any number, or function, divided by itself becomes 1.

Answer 2

Well, any number or function except those that evaluate to 0. 0/0 is undefined. :)

Answer 3

no, i mean e^x * e^x

Answer 4

When you multiple two of the same bases together, you always add their exponents together....

Answer 5

they have the same base so add the exponents
e^(x+x)=e^(2x)
