# What is the minimum value of the sum of their squares if the sum of two numbers is K?

So to start off, set each number equal to a variable. (In this case, I will use x= 1st number and y= 2nd number) Since the sum of the two numbers is K... x+y=K Therefore y=K-x And the sum of their squares is a minimum... x^2+y^2=MINIMUM Therefore = x^2+(K-x)^2 So to simplify... ( Full Answer )

# How do you get the square root of a perfect square?

you find what same 2 numbers equal that number EXAMPLE: what is the square root of 49? ANSWER:7 because 7x7=49 Edit: Nearly there. 7 is the PRINCIPAL square root but there is another, which is -7. (-7)*(-7) is also 49.

# How do you get the square root of not perfect square?

One way is to solve the equation x^2 - number = 0 with Newton's method. Start with a guess for the answer (say your number is 20, guess 5 or something - it hardly matters how bad your guess is). Say your guess is G. Then compute : 0.5 * (G + 20/G) This will give you a new guess. Rinse and repe ( Full Answer )
