Radicals and Complex Numbers Need Help
We are not here to do all your homework for you.
I will say that if there is not a squared term under a square root sign then the expression cannot be simplified.
sqrt(14) There is no squared number (other than one and that does not count) under the square root so you cannot simplify it.
sqrt(72)=sqrt(36*2) 36 is a square number so you can simplify it to sqrt36 * sqrt2 = 6sqrt2
Please leave Turtle to answer the rest for him/herself
