Best ResponseYou've already chosen the best response.0Actually the original problem is the square root of 5 divided by the square root of 8x. Can you show the whole process because I'm really confused

Best ResponseYou've already chosen the best response.2\[\frac{\sqrt5}{\sqrt{8x}}=\frac{\sqrt5}{\sqrt{2^3x}}\cdot\frac{\sqrt{2x}}{\sqrt{2x}}=\frac{\sqrt{10x}}{4x}\]

Best ResponseYou've already chosen the best response.0Why don't i multiply the numerator and denominator by the swuare root of 8x?? why do i have to break it up

Best ResponseYou've already chosen the best response.2\[\frac{\sqrt5}{\sqrt{8x}}=\frac{\sqrt5}{\sqrt{8x}}\cdot\frac{\sqrt{8x}}{\sqrt{8x}}=\frac{\sqrt{40x}}{\sqrt{64x^2}}=\frac{2\sqrt{10x}}{8x}=\frac{\sqrt{10x}}{4x}\]

Best ResponseYou've already chosen the best response.0wait i thought you said \[\sqrt{8x } * \sqrt{8x} = 8x\]

Best ResponseYou've already chosen the best response.2yeah it does, look at the denominator. it winds up as 8x, then simplifies to 4x

Best ResponseYou've already chosen the best response.0and on the last step you just divided the top and bottum by 2 to get rid of it?
