Timesing negative powers
WebThere are several rules that you will need to know. Rule 1. When you multiply indices of the same number you add the powers. For example: 54 x 53 = 54 + 3 = 57. Rule 2. When you divide indices of the same number you subtract the powers. Rule 3. Indices outside a bracket multiply. For example: (32) 4 = 32 x 4 = 38. WebSo a negative power gives the reciprocal of the number — that is, 1 over the number. Thus 4−2 = 1/42 = 1 16, and 4−1 = 1/41 = 1 4. Similarly, 3−2 = 1 32 = 1 9 and 5−3 = 1 53 = 1 125. A common misconception is that since the power is negative, the result must be negative: as you can see, this is not so. Now we know that 40 = 1 and 41 ...
