I have a problem here. This is a homework were I have to solve the roots and order them from greatest to least. But specifically, my problem is with the roots greater than square. I have no idea how to solve them. I know how to solve square roots, but roots greater than square seem to have different way of solving, and I can't solve them. No idea. Can anyone please help me with these?

The order will be the same if you raise the power of each by the same amount. Express as fractional exponents first. I'll help with the first... multiply by the LCD of the exponents. That would be 10. Now it should be obvious.

Once you have converted a fifth root (for example) into an exponent of 1/5, just put 2^(1/5) (for example) into Google to find its value. Finally, order the resulting values.
