Hi, I am planning on taking the Teacher Certification Exam and I am studying to get ready for the test. I was wondering if you can help me with two problems though. I just have a quick question on one of them as a matter a fact. What if they give you a fraction and the exponent is also a fraction but the exponent is not a negative. Does that one go on the numerator? Its 4/5x to the power of 3/2. I ended up putting the fraction exponent on the bottom. Meaning that its 4/5square root of x to the power of 3.

On the next problem its .2x^-2/3+3/(7x^-1/2). I already know what to do for .2x^-2/3. The only question that I have on this one is if I have a negative exponent for the denominator does it turn positive and go up to the numerator? Thanks
