1. **State the problem:** Multiply $2y^2$ by $2y^2$.
2. **Write the expression:**
$$2y^2 \times 2y^2$$
3. **Multiply the coefficients (numbers):**
$$2 \times 2 = 4$$
4. **Multiply the variables with exponents:**
When multiplying powers with the same base, add the exponents:
$$y^2 \times y^2 = y^{2+2} = y^4$$
5. **Combine the results:**
$$4y^4$$
**Final answer:**
$$4y^4$$
Multiply Y Squared Aa4941
