Best ResponseYou've already chosen the best response.0In this case, it's not so nice because you don't have things you can easily divide. But fractional exponents are valid notationally

Best ResponseYou've already chosen the best response.0So \[\sqrt[3]{a^2} = a^{\frac{2}{3}}\]

Best ResponseYou've already chosen the best response.0Wait, the original expression you have is \[\sqrt[3]{50x^2z^5} \times \sqrt[3]{15y^3}\] ?

Best ResponseYou've already chosen the best response.0yeah. because i broke 50 into radical 25 and and 2

Best ResponseYou've already chosen the best response.0Ok, so yes. If you bring the insides of both together you can factor out a 5 and a z.

Best ResponseYou've already chosen the best response.0So the only problem is that you should have a y and a z on the outside as well.

Best ResponseYou've already chosen the best response.0\[\sqrt[3]{50*15x^2y^3z^5} = \sqrt[3]{6*5^3x^2y^3z^3z^2}\] And we take out everything with a power of 3. \[= 5yz*\sqrt[3]{6x^2z^2}\]

Best ResponseYou've already chosen the best response.0All of this is just remembering your rules for exponents when you multiply or raise to a power. a \[a^b*a^c = a^{b+c}\] \[(a^b)^c = a^{b*c}\]
