I needed to edit this question

OpenStudy (batman*):

???

jhonyy9 (jhonyy9):

sqrta *sqrtb = sqrt(a*b)

OpenStudy (g33k):

I had to type it, I need help on simplify and multiplying that equation please

jhonyy9 (jhonyy9):

\[\sqrt{7x}(\sqrt{x-7\sqrt{7}}) = \sqrt{7x*x -7*\sqrt{7x*7}} = \]

jhonyy9 (jhonyy9):

can you continue it ?

OpenStudy (g33k):

No :/

jhonyy9 (jhonyy9):

7x*x=7x^2 yes ?

OpenStudy (g33k):

yeah

jhonyy9 (jhonyy9):

7x*7 = 49x so there will be 7sqrt49x but you know that sqrt49 = 7 so than will result 7*7sqrtx = 49sqrtx - ok ?

OpenStudy (g33k):

Okay

jhonyy9 (jhonyy9):

so continue it and now inside radical will be sqrt(7x^2 - 49sqrtx ) - yes ?

OpenStudy (g33k):

Yeah

jhonyy9 (jhonyy9):

do you can continue it now ?

OpenStudy (g33k):

I think so, thanks :)

jhonyy9 (jhonyy9):
