The power (1) |
1. Concept of the power
When we see the picture, we wonder: how many oarsmen participate in the regattas? There are 4 oarsmen in each of the four trawlers, then in total there are 4 x 4 = 16 oarsmen, This can also be written as: 4^{2} and it is read "four to the power of two" .
The powers are products that are all equal factors.
Example: 5 x 5 = 5^{2}; 6 x 6 x 6 = 6^{3};
7 x 7 x 7 x 7 = 7^{4}.
Do these problems on a paper and write the solution:
