→Decomposition: Used exponent notation to make decomposition clearer. |

Line 72:
In some cases an exponential notation is used:
:<math>v^{\odot k}=\underbrace{v\odot v\odot\cdots\odot v}_{k\text{ times}}=\underbrace{v\otimes v\otimes\cdots\otimes v}_{k\text{ times}}=v^{\otimes k}.</math>
Where ''v'' is a vector.
Again, in some cases the '<math>\odot</math>' is left out:
:<math>v^k=\underbrace{v\,v\,\cdots\,v}_{k\text{ times}}=\underbrace{v\odot v\odot\cdots\odot v}_{k\text{ times}}.</math>
