Indices law  - Law 1

`a^n=(a)(a)\ ...\  ...\  .(a)` 

To remember this try simple numbers you know first.

So something we know here is `2^2`

`2^2=2\times2=4`

`2^8=2\times2\times2\times2\times2\times2\times2\times2`

`2^8=256`

Further example

`x^3` is the same as `x\times\x\timesx`

                          Or `(x)(x)(x)`
