√320 over √8

steps please

OpenStudy (anonymous):

√320 / √8 sqrt (8*8*5) /sqrt(8) sqrt(40)

OpenStudy (watchmath):

\(\frac{\sqrt{320}}{\sqrt{8}}=\sqrt{\frac{320}{4}}=\sqrt{80}=\sqrt{16\cdot 5}-4\sqrt{5}\)

howd u get 320/4 on the second step

OpenStudy (watchmath):

Sorry I made a typo, just use wink_pink answer :)

OpenStudy (anonymous):

OpenStudy (watchmath):

Ok it should be \(\sqrt{\frac{320}{8}}=\sqrt{40}=\sqrt{4\cdot 10}=2\sqrt{10}\)

OpenStudy (anonymous):

I have no clue how u got tht

OpenStudy (anonymous):
