The principal square root is the nonnegative number that when multiplied by itself equals aa. The square root obtained using a calculator is the principal square root.The principal square root of aa is written as √aa. The symbol is called a radical, the term under the symbol is called ...
Since a square root has two values, one positive and the other negative w2 - (7/4)w + (7/2) = 0 has two solutions: w = 7/8 + √ 175/64 • i or w = 7/8 - √ 175/64 • i Note that √ 175/64 can be written as √ 175 / √ 64 which is √ 175 / 8 Solve...
If x2 = y, then x is a square root of y. From this definition we have seen that every positive number has two square roots, one positive and one negative. Recall these definitions from chapter 7. The principal square root of a positive number is the positive square root. The symbol ...
