 Question 548109: (8^2/3*27^3/2)/(16^3/4*9^3/4) the 2/3 etc are fractional exponents (indices) not actual fractions I cannot seem to work this out. I have tried with the algibrator program but it seems to take a million steps for what at first appears to be a not too complicated problem. I have tried to reduce the whole numbers to , for example 8 to 2^4 etc. I do not know if this will appear correctly in the text so I will describe the problem. 8 with the fractional indices 2 over 3 times 27 with the fractional indices 3 over 4 all over 16 with the fractional indices 3 over 4 times 9 with the fractional indices 3 over 4 Click here to see answer by oberobic(2304)

 Question 548145: Compare and contrast doing operations (adding, subtracting, multiplying, and dividing) with rational expressions to doing operations with fractions. Can understanding how to work with one kind of problem help understand how to work another type? How do we find the greatest common factor of a polynomial? Demonstrate the process with an example showing your work. When finding the greatest common factor of a polynomial, can it ever be larger than the smallest coefficient? Describe the mathematic process of canceling like factors when working with rational expressions & demonstrate this with an example. Click here to see answer by richard1234(5390)

 Question 548503: Essay; show all work. Add the following polynomials: (1/10x^2 – 1/2x(-3/10))+(1/2x^2+1/4x(-1/5)) I got 3/5x^2-1/4x-1/2, but that just doesn't seem right. Essay; show all work. Find the product: (1/3x^2-2/3)*(1/2x -1/2) For this one I have: 1/3x2 * 1/2x* -2/3 -1/2= 1/6x3 * 1/3=1/6x^3 * 1/3=1/6x3 * 1/3 Again, this just doesn't seem right. I have no clue what I am doing. The textbook gives one example and that was of no help at all. My teacher gets frustrated when asked questions and acts like she's been ignored, when it's just a simple thing of not getting it. Can someone please help me out with this??? Click here to see answer by stanbon(57979)
