Question 180615
<font face="Times New Roman" size="+2">


*[tex \Large 7 + sqrt{2x - 1} = 10]


Add -7 to both sides:


*[tex \Large sqrt{2x - 1} = 3]


Square both sides


*[tex \Large 2x - 1 = 9]


You should be able to take it from here.


============================================================


*[tex \Large 4(x - 9)^{1 \over 3} = 8]


Multiply both sides by *[tex \Large {1 \over 4}]:


*[tex \Large (x - 9)^{1 \over 3} = 2]


Raise each side to the 3rd power: 


*[tex \Large x - 9 = 8]


You can do the rest.
