Question

Can anyone help me simplify square roots? I have some sort of mental brick wall refusing to let me understand them, Thanks!

Answer 1

start at simple numbers
the square root of 4 is 2 because 2 * 2 = 4

Answer 2

yes

Answer 3

4 is a perfect square beacuse its square root is an integer

Answer 4

it also as another square root -2
because -2*-2 = 4

Answer 5

another example would be the square roots of 25 which are 5 and -5

Answer 6

Okay

Answer 7

when it comes to other numbers which are not perfect squares there is not an easy way to find the square roots by hand but we have a marvallous little machine called a calculator to do it for us
eg square root of 14 on my calculator is 3.741657387

Answer 8

there are no real square roots of a negative number because no 2 real numbers multiplied together would give a negative

Answer 9

the square roots of fractions :-

square root of 1/4 is 1/2 or -1/2
