Answer:
Explanation below.
Step-by-step explanation:
1. a. ![\sqrt{x} =12](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D12)
b. ![\sqrt{x} ^{2}=12^{2}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%5E%7B2%7D%3D12%5E%7B2%7D)
c. x=144
2. a. ![\sqrt{x^{2} } =\sqrt{196}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E%7B2%7D%20%7D%20%3D%5Csqrt%7B196%7D)
b. x= 14
3.
![\sqrt{x} -4 +4= 8+4\\\sqrt{x} =12\\x= 3.46410161514 \\or \\2\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-4%20%2B4%3D%208%2B4%5C%5C%5Csqrt%7Bx%7D%20%3D12%5C%5Cx%3D%203.46410161514%20%20%5C%5Cor%20%20%5C%5C2%5Csqrt%7B3%7D)
4.
![2(x^{2} +3)=398\\x^{2} +3= 199\\x^{2} =196\\x=14](https://tex.z-dn.net/?f=2%28x%5E%7B2%7D%20%2B3%29%3D398%5C%5Cx%5E%7B2%7D%20%2B3%3D%20199%5C%5Cx%5E%7B2%7D%20%3D196%5C%5Cx%3D14)
