Does square root flip inequality
WebSolving Radical Equations Algebraically. Now let’s solve some problems with square root functions. With even radicals, we have to make sure that our answers never produce a negative number underneath the square root (even radical) sign.Also, if we raise both sides to an even exponent (like squaring), we need to check our answers, since some … WebMar 1, 2024 · For example, you might end up with. 5 < 4 {\displaystyle 5<4} . This is an untrue statement because 5 is not less than 4. 2. Reverse the inequality sign if you multiply or divide by a negative number on both sides. Addition and subtraction never change the direction of the inequality sign.
