Thus , 25 has two equal factors , 5 and 5 ; hence the square root of 25 is 5 . This
is written V25 = 5 . In the same way , V x2 = x . Similarly , if there are three equal
factors of a number , either of them is called the cube root of that number .

Four different cases are here possible and will now be illustrated . ( 1 ) Consider
the product 5X4 . This means , as in arithmetic , that 5 is to be taken 4 times .
Hence the result is 20 ; that is , 5X4 = 20 . ( 2 ) Consider the product ( - 5 ) X4 .
