No change $f ' ' ' ' \left(x\right) = - 5 {e}^{x}$
#### Explanation:
Just derive it 4 times
Rule for deriving ${e}^{x}$
$f \left(x\right) = {e}^{x} \Rightarrow {e}^{x}$
$f \left(x\right) = - 5 {e}^{x}$

# What is the formula of (a-b)^4?
Math Staff asked 4 months ago
$\ (a-b)^4 = a^4 – 4a^3b + 6a^2b^2 – 4ab^3 + b^4$
#### Explanation:
$\ (a-b)^4 = (a-b)^2 \times (a-b)^2$
$\ (a-b)^2 = a^2 + b^2 – 2ab$
$\ (a-b)^4 = (a^2 + b^2 – 2ab) \times (a^2 + b^2 – 2ab)$
Multiplication
