How to times indices with fractions
Then we add the opposites of the positive fractions, so that our number system now contain all numbers such as − and − = −4. All these numbers together are called the rational numbers − the word ‘rational’ is the adjective from ‘ratio’. We have actually been using negative fractions in these notes for some time. Indices show where a number has been multiplied by itself, eg squared or cubed, or to show roots of numbers, eg square root. Some terms with indices can be simplified using the laws of indices. ♫ "Multiplying fractions: no big problem, Top times top over bottom times bottom.
