little bit of help

[rewsswerx]

Hello, im doing my first course in university and can't understand the task. Could any kind soul help me with it? I already appreciate it very much.

Write a program that calculates an entire number from 1 to 20 square root. Display the result in a table for n grades (n, n 2, n 3). Display the square root values by 3 digits after commas.

<cmath> has sqrt. If you are supposed to cook up your own, a web search on that should show you how, its about 10 lines of code.
something did not translate so its a little fuzzy beyond that...
