in this lesson we're gonna focus on simplifying radicals so let's say if we have the square root of 36 the square root of negative 49 negative square root of 64 a negative square root of negative 25 how would you simplify these for radicals the square root of 36 is simply 6 it's a real number the square root of a negative number is not a real number it's an imagined number so this is equal to 7 I where I is the square root of negative 1 if you haven't learned about major numbers you can not worry about it so this doesn't give you a real number it gives you an imaginary number but the way you show your work though here's what you can do first separate the 49 and the negative 1 the square root of 49 is 7 and the square root of negative 1 is I so you get 7 I the square root of 64 is 8 but as a negative in front so it's negative 8 now for this one we have negative square root 25 times the s
