In square root x+7=1

I get this far and then get stuck, can you help me?

In square root x+7=1

e=square root x+7

e^2=x+7

x+7=e^2

x=e^2-7

**Steve**, Saturday, January 5, 2013 at 12:18amthe answer is exact. Going any further would just be to approximate it with a decimal. e^2-7 is just as good as π/4 or √23-ln(3).

It's just a number.
