Question

PLEASE HELP!!! I have to rationalize the denominator of this expression, would square root 5 divided by square root 8x be square root 40x over 8x?

Answer 1

Like would : \[\frac{ \sqrt{5}}{\sqrt{8x} }\] become: \[\frac{ \sqrt{40x} }{ 8x }\] ???

Answer 2

Yes, because
\[\sqrt{5} * \sqrt{8x} = \sqrt{5*8x} = \sqrt{40x}\]

Answer 3

okay, thank you so much @DDCamp!
