WebSuppose you are asked to find the sum of all integers between √200 and √300. Then the solution requires finding the nearest perfect squares in order to use their square roots as bounds, as follows: 14 = √196 < √200 < x < √300 < √324 = 18. Then the only possible values of x are 15, 16, and 17. 15 + 16 + 17 = 48.

Web( 3 votes) David Severin 6 years ago FIrst off, we cannot have a negative on any of our even roots (square, 4th, 6th, etc.) without getting into imaginary numbers. So if you are asking (-.5)^ (1/5) we could write the square root sign with a raised 5 on the crook of the root sign, and a -.5 inside. Hope this helps.
