Best ResponseYou've already chosen the best response.0Raise both sides to the 5/3 power (x9)=8^(5/3)=32 x9=32 x=41

Best ResponseYou've already chosen the best response.0\[\sqrt[5]{(x9)^2} = (x9)^{3/5}\]

Best ResponseYou've already chosen the best response.0sorry, should be \[\sqrt[5]{(x9)^{3}}\]

Best ResponseYou've already chosen the best response.0Now\[[\sqrt[5]{(x9)^{3}}]^{5} = [8]^5\] \[(x9)^3 = 8^5\] \[\sqrt[3]{(x9)^3} = \sqrt[3]{[8^5]}\] \[x9 = 8^{5/3}\]

Best ResponseYou've already chosen the best response.0so x9 = 32 add 9 both sides x9+9=32+9 x=41 hope it helps!

Best ResponseYou've already chosen the best response.0lets try this. rather than raising to the fifth power first, take the cube root of 8 first. the cube root of 8 is 2, and 2 to the fifth power is 32. much easier that way.
