## anonymous 4 years ago Solve (5x-4)^1/2=6

1. anonymous

Square both sides, solve for x

2. anonymous

$(\sqrt{5x-4})^2=6^2$

3. anonymous

My options are x=2, x=4, x=8, or none of the above

4. anonymous

What is the squart root of a number squared?

5. anonymous

idkk ?

6. anonymous

$(\sqrt{x})^2=x$

7. anonymous

Use that rule to solve for x in your equation

8. anonymous

There is no sqrt in this

9. anonymous

x^(1/2)=$\sqrt{x}$

10. anonymous

So none of the above

11. anonymous

I'm trying to explain.

12. anonymous

Do you understand that x^(1/2) is the sqrt of x?

13. anonymous

yes

14. anonymous

So there is a sqrt in this problem, then...

15. anonymous

look at my first response, can you figure that out?
