SOLUTION: my problem is: 3x^(3/4)=192. i divided both sides by 3 (since the fractional exponent was only for the x) => x^(3/4)=64. after that i have no clue what to do. please help me!

Question 22909: my problem is: 3x^(3/4)=192. i divided both sides by 3 (since the fractional exponent was only for the x) => x^(3/4)=64. after that i have no clue what to do. please help me! this is for my take home final for my algebra II class. and i really need to pass it!

Divide both sides by "3" to get x^(3/4) = 64.
Raise both sides of the equation to the(4/3) power to get
x = 64^(4/3)
The 3rd root of 64 is 4.
Then 4^4 = 256
So x = 256
