-7.. square root cancels out square
Ordinarily, the square root of -70 does not exist since a positive number squared or a negative number squared results in a positive number. If complex numbers are permitted, then the square root of -70 is i√70 ~= 8.367i where i is the imaginary square root of -1 such that i2 = -1.
Remember when taking the square root of a number, that there is the positive answer, but also there is a negative numbert answer. An example is the square root of 49 can be either 7 or negative seven, because when you multiply negative seven times itself, you get forty nine.
well, the square root of 81 is 9, and seven squared is 49, so it wud be 40

That simply means that there is both a positive and a negative number which, when squared, gives you 64.

If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
Square root of s, or negative square root of s.
Yes.
Because the square root of -25 would be that number that, squared, would equal -25. No number, positive or negative, can result in a negative square. Since -25 is a negative number, no number, positive or negative, can be squared to equal -25.
Negative numbers can't be squared rooted but the positive square root of 484 is 22

no,a negative number cannot have a square root .it is made only for positive numbers .but,yes,negative numbers can be squared.
(x - i)(x + i) where i is the imaginary square root of negative one
The square root of A2 is... A !
