Question 60914: I can only solve part of this equation and then I get stuck. Can someone show me the next steps I need to take and explain how they are done? I have done the equation as far as I can:
SQRT(2X-1)+SQRT(X-4)= 4 <----original equation
SQRT(2X-1)=4-SQRT(X-4)
(SQRT<2X-1>)^2 = (4-SQRT)^2
2X-1 = (4-SQRT)(4-SQRT) <------I am lost as to how to solve finish this side of the equation.
Thanks!

Question 61332: How do I figure out the problem:
4_/--(square root sign)
10
* (multiplied by)
7_/--
15 ??
(4 and 7 being the index and 10 and 15 being the radicand.)
I need help step by step, because I do not understand how to figure this with the index in there. Thank you.
