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
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?
