WebSquare Root Notation. √mis read “the square root ofm”. Ifn2 = m, thenn = √m, forn ≥ 0. We know that every positive number has two square roots and the radical sign indicates the positive one. We write √169 = 13. If we want to find the negative square root of a number, we place a negative in front of the radical sign. For example ...

WebWhen taking the square roots of variables, divide the exponent by 2. For example, √x 8 = x 4, because you divide the exponent 8 by 2. This follows from the power of a power rule of exponents, (x 4) 2 = x 8. When squaring, multiply the exponent by two, so when taking a square root, divide the exponent by 2. This is shown in the following example. WebBut there is an even more powerful method... we can combine the exponent and root to make a new exponent, like this: n√am= amn The new exponent is the fraction mnwhich may be easier to solve. Example: 3√46= 463 = 42 = 16 This works because the nth rootis the same as an exponent of (1/n) n√a= a1n Example: 2√9= 912= 3 greg courtright attorney wv
