Can square roots be added to each other
WebAug 1, 2024 · As other answers already point out, the negative number can be considered a square root of its positive square, but is not the principal square root that is usually notated with the z sign. The square root of a purely imaginary number is a complex number on one of the lines at 45° angles to the real and imaginary axes. WebSep 13, 2024 · When we see two radicals next to each other like this, it means we’re supposed to multiply them. To multiply two square roots, we just multiply the radicands and put the product under a radical sign. That is, the product of two square roots is equal to the square root of the product of the radicands.???\sqrt{3\cdot2}?????\sqrt{6}???
