The principal square root is the non-negative square root.
never a negative
And its negative counterpart.
Well yes. I love lamp, was a good one. He really likes cats. So does the muffin man.
Because in real numbers they are not defined.
The second root would be the negative of the principal root.
The principal root of a number is the positive real square root of the number - if it exists. Since -25 is negative, it does not have a real square root. Its square roots are the imaginary numbers +/-5i where i is the [imaginary] square root of -1. i is neither positive nor negative and so neither +5i nor -5i is a principal root.
A positive number has two square roots, its principal (positive) root and its negative root. This is because a negative number multiplied by a negative number equals a positive number. In this instance, the square roots of 256 are 16 and -16.
There are no explicit symbols. The non-negative square toot is called the principal square root.
DEAR SIR, I will request you to ........ If reply is positive then ? "Thank you, sir." if reply is negative then ? "How dare you?"
Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.
