... Similarly , we have 5x - 3x = 2x . Thus , we see that in order to subtract like numbers all we need to do is to subtract the coefficients to obtain a new coefficient , and then multiply the result by the common factor . ORAL EXERCISES ...

... Similarly , if there are three equal factors of a number , either of them is called the cube root of that number . Thus , 64 has three equal factors 4 , 4 , and 4 ; hence the cube root of 64 is 4. This is written 64-4 . √x3 = x . C In ...
