Answer:
The answer is 4a
Step-by-step explanation:
1) Simplify 4a² + 12a² to 16a².
![\sqrt{ {16a}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B16a%7D%5E%7B2%7D%20%7D%20)
2) Use this rule:
![\sqrt{ab} = \sqrt{a} \sqrt{b}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bab%7D%20%20%3D%20%20%5Csqrt%7Ba%7D%20%20%5Csqrt%7Bb%7D%20)
![\sqrt{16} \sqrt{ {a}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%7D%20%20%5Csqrt%7B%20%7Ba%7D%5E%7B2%7D%20%7D%20)
3) Since 4 × 4 is 16, the square root of 16 is 4.
![4 \sqrt{ {a}^{2} }](https://tex.z-dn.net/?f=4%20%5Csqrt%7B%20%7Ba%7D%5E%7B2%7D%20%7D%20)
4) Simplify.
