solve a radical expression: 1.5r250 (*r denotes the radical symbol) in a radical expression where the index of the root is 1.5 and the number is 250 Use Calculator, Show Steps 2. Relevant equations 3. The attempt at a solution First of all, using a calculator the answer comes out to 39.685, but I can't really show the steps since the calculator has an XsqrtY button and simply shows the answer. I attempted to find the steps as below, I know this is wrong since I took the square after breaking down the 250....please help. 1.5 r 250 = 1.5 r 10 * 25 1.5 * 5 r 10 7.5 r 10 7.5 * 3.162 23.715 (my answer) is not 39.685 (Scientific calculator answer) I can't figure out the steps to solve this without the calculator, and I can't come up with the right answer. How do you solve a radical expression where the index is not 2 (square) or 3(cube), but 1.5 instead?
