With the definition of zero and negative indices,
${{a}^{0}}=1$ and ${{a}^{-n}}=\frac{1}{{{a}^{n}}}$
we can now extend all the 5 laws of indices to include all integer indices. (positive, zero and negative)

With the definition of zero and negative indices,

${{a}^{0}}=1$ and ${{a}^{-n}}=\frac{1}{{{a}^{n}}}$

we can now extend all the 5 laws of indices to include **all integer indices.** (positive, zero and negative)
