Power of Fractions
From chapter 1 we know that power is a kind of recurrent multiplication by the same factor. For example, 24 = 2 × 2 × 2 × 2 = 16. The same approach can be used in fractions as well. Thus, for example we can write
(3/5)2
= 3/5 × 3/5
= (3 × 3)/(5 × 5)
= 9/25
In general, we can writeRemark! When you are dealing with mixed numbers or integers, it is better to have them written as fractions, as it is a category that includes all these numbers. For example, if we have
5 × 2 1/3
we cannot write the result as 10
1/3 but convert both numbers as fractions and then make the operation. Thus, we have
5 × 2 1/3 = 5/1 × 7/3 = 35/3 = 11 2/3
As you see, we obtain a different result, so the first method (multiplying the whole parts separately) is wrong.
