 Question 174247: I don't know how to type this, so I'll try to explain it. Square root symbol, with 6 outside (but inside the little section), and inside the square root is another square root symbol. Inside this second square root symbol is a 2. Now subtract from that: square root with 12 inside the little part, and inside the square root is 2 with exponent of 13. Hope this makes sense. Thanks!

 Question 173157: thi is actually a problem from a exam. It is my study for my final but i got it wrong. (125x^6y)3\4 /(8x^2y^4)-1\3 This what I did, (5x^2y^3)2=25x^4y^6 that's what I got for my first answer. for the bottom fraction I did the following: 1/(8x^2y^4)1/3 My aswer was 25x^4y^6/2x^2/3y^4/3 but the answer was 25x^10/3 all over 2y^2/3 please help,i do not know how to get that answer. On the bottom equation I did not know what to do, because the Index was a negative one over 3. Pleas help is for my final. thank you. Click here to see answer by checkley77(12569)
