write it as

now what?

and if your power has more than one character, you must keep them in {} brackets, that is, type x^{0.5} and x^{3/2} as opposed to what you typed. also, you should be aware that LaTeX removes spaces, so that's why what you typed looked so messy. use ~ to insert spaces, or type your text messages in a \text {} or \mbox {}

(2/3)*x^(3/2) + (-1/2)*6*(x^(-2)) = (2/3)*x^(3/2) -3*(x^(-2))
