`f^(prime)(x)=varphi^(prime)(x)=f(x)` for all `xdot` Also, `f(3)=5a n df^(prime)(3)=4.` Then the value of `[f(10)]^2`− [ϕ(10)]^2is _____

Explanation

To solve the problem step by step, we start with the given information:

1. **Given Equations**:
- \( f'(x) = \varphi'(x) = f(x) \) for all \( x \)
- \( f(3) = 5 \)
- \( f'(3) = 4 \)

2. **Objective**:
...
