**drwls**, Saturday, May 29, 2010 at 2:10amsqrt(5/3) cannot be simplified.

Neither can (sqrt3)/5

sqrt[8x^5*(3x^2)^2]

= 3x^2*sqrt(8x^5)

= 3x^2*sqrt[(4x^4)*(2x)]

= 6x^4*sqrt(2x)

You need to use parentheses and brackets to clarify the order of operations, otherwise the expressions you write can have different values.
