The first power of any number is this number. Extraction of a root – an operation of finding a base of a power by the power and its exponent: Here 243 – a radicand, 5 – an index (degree) of the root, 3 – a value of the root. The second root is called a square root, the third root – a cube root.The second degree of square root isn’t written: Addition and subtraction, multiplication...
