The given expression is:

$12e^{-3t} + 16e^{-8t} + 14e$

This expression contains three exponential terms. The first two terms have exponents involving the variable $t$, while the last term is a constant involving Euler's number $e$ (approximately 2.71828). To break this down:

1. $12e^{-3t}$: An exponential decay term with coefficient 12 and exponent $-3t$.
2. $16e^{-8t}$: Another exponential decay term with coefficient 16 and exponent $-8t$.
3. $14e$: This is a constant term because it involves only Euler's number and has no variable $t$ in the exponent.

This expression is in its simplified form unless you're asked to do specific operations, such as factoring or solving for $t$.
