How to solve negative square roots
WebNegative Exponent Rule 1: For every number “a” with negative exponents “-n” (i.e.) a -n, take the reciprocal of the base number and multiply the value according to the value of the exponent number. a − n = 1 a n = 1 a × 1 a × … n t i m e s. For example, 4 -3. Here, the base number is 4 and the exponent is -3. WebMay 12, 2024 · When you have ( x − 9 2) 2 = 0, instead of taking the square root, you should expand the binomial: ( x − 9 2) ( x − 9 2) = 0 So x = 9 2. This is sometimes called a double root. By mistakenly taking the square root, you introduced the negative term, which was never there in the first place.
