Answer:
![- 40 \sqrt{x}](https://tex.z-dn.net/?f=%20-%2040%20%5Csqrt%7Bx%7D%20)
Step-by-step explanation:
We want to simplify:
![\sqrt{5} \times - 4 \sqrt{20x}](https://tex.z-dn.net/?f=%20%5Csqrt%7B5%7D%20%20%5Ctimes%20%20-%204%20%5Csqrt%7B20x%7D%20)
We rewrite the radicand using prime factorization:
![\sqrt{5} \times - 4 \sqrt{4 \times 5x}](https://tex.z-dn.net/?f=%20%5Csqrt%7B5%7D%20%20%5Ctimes%20%20-%204%20%5Csqrt%7B4%20%5Ctimes%205x%7D%20)
This gives us
![\sqrt{5} \times - 4 \sqrt{4} \times \sqrt{5} \times \sqrt{x}](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D%20%20%5Ctimes%20%20-%204%20%5Csqrt%7B4%7D%20%20%5Ctimes%20%20%5Csqrt%7B5%7D%20%20%5Ctimes%20%20%5Csqrt%7Bx%7D%20)
Create perfect squares and simplify:
![(\sqrt{5} )^{2} \times - 4 \sqrt{4} \times \sqrt{x}](https://tex.z-dn.net/?f=%28%5Csqrt%7B5%7D%20%29%5E%7B2%7D%20%20%20%5Ctimes%20%20-%204%20%5Csqrt%7B4%7D%20%20%20%5Ctimes%20%20%5Csqrt%7Bx%7D%20)
![5 \times - 4(2) \sqrt{x}](https://tex.z-dn.net/?f=5%20%5Ctimes%20%20-%204%282%29%20%5Csqrt%7Bx%7D%20)
![5 \times - 8 \sqrt{x} = - 40 \sqrt{x}](https://tex.z-dn.net/?f=5%20%5Ctimes%20%20-%208%20%5Csqrt%7Bx%7D%20%20%3D%20%20-%2040%20%5Csqrt%7Bx%7D%20)
