$e^1.8~~6.04965$

The value of $e^x$ is given by

$1+x+x^2/(2!)+x^3/(3!)+x^4/(4!)+x^5/(5!)+...............................$

Hence $e^1.8$ is given by

$1+1.8+1.8^2/(2!)+1.8^3/(3!)+1.8^4/(4!)+1.8^5/(5!)+...............................$

This is a well known convergent series and result is the irrational number $e^1=e=2.7182818284590452353602874713527........$

and one can also find $e^1.8$ using a scientific calculator, which
is roughly $~~6.04965$
