Simpify the following radicals.

Would that be 9x

http://www.mathgoodies.com/forums/im..._math_cbrt.gif-125chttp://www.mathgoodies.com/forums/im...math_cubed.gif

Would that be -5c

Write ^7http://www.mathgoodies.com/forums/im..._math_sqrt.gifxhttp://www.mathgoodies.com/forums/im...math_cubed.gif by using rational exponents rather than radical notation.

Use the laws of exponents to simplify. (x^-2/3 y)http://www.mathgoodies.com/forums/im...math_cubed.gif

Find the domain of the given function. F(x)= http://www.mathgoodies.com/forums/im..._math_sqrt.gif2x-3

The 2x-3 is under the radical sign.

Thanks
