distribute

OpenStudy (danjs):

\[8*\sqrt{5}+ 3*\sqrt{6}\sqrt{5}\]

OpenStudy (danjs):

recall: \[\sqrt{a}\sqrt{b} = \sqrt{a*b}\]

OpenStudy (danjs):

what does that do to the expression if you combine roots like that?

OpenStudy (sparklestaraa):

change it maybe I'm sorry i don't understand

OpenStudy (danjs):

the square root of 6 times the square root of 5 = the square root of (6 * 5)

OpenStudy (danjs):

\[\sqrt{5}(8 + 3\sqrt{6})\] distribute the root(5) by multiplying it to each term \[8 * \sqrt{5} + 3\sqrt{6}\sqrt{5}\] combine the root 6 and root 5

OpenStudy (danjs):

\[\sqrt{6}\sqrt{5} = \sqrt{6*5} = \sqrt{30}\]
