1. **State the problem:** Simplify the expression $3(-3)-4-5(-3)2^2$.
2. **Recall order of operations:** Calculate exponents first, then multiplication and division from left to right, and finally addition and subtraction from left to right.
3. **Calculate the exponent:**
$$2^2 = 4$$
4. **Substitute back:**
$$3(-3) - 4 - 5(-3) \times 4$$
5. **Calculate each multiplication:**
$$3 \times (-3) = -9$$
$$5 \times (-3) = -15$$
6. **Substitute these values:**
$$-9 - 4 - (-15) \times 4$$
7. **Calculate the remaining multiplication:**
$$-15 \times 4 = -60$$
8. **Substitute:**
$$-9 - 4 - (-60)$$
9. **Simplify the subtraction of a negative:**
$$-9 - 4 + 60$$
10. **Perform the addition and subtraction from left to right:**
$$(-9 - 4) + 60 = -13 + 60 = 47$$
**Final answer:**
$$47$$
