Find the square roots of 2500. What is the principal square root of 2500?
50
50
postive or negative 50
the square root of a positive number is always plus/minus some other number. e.g.:\[\sqrt{25}=\pm5\]
every two
It should be positive since it's asking the principle of square root...
so try and break up your number into components you can handle. e.g. 2500 = 25 * 100 and use the fact that:\[\sqrt{ab}=\sqrt{a}*\sqrt{b}\]
ok What is the negative square root of 2500?
@Darkmirror - the first part of the question states "Find the square roots..." - which means find both (I think)
@asnaseer ~ yup ~joyce ~ the negative one is -50

yw
it depends where u are,here the square root of a positive number is always positive,the negative sqrt is simply -sqrt(of the number)
