Indices law - Law 1

$a^n=(a)(a)\ ...\ ...\ .(a)$

A positive is to multiply

To remember this try simple numbers you know first.

So something we know here is $10^2$

$10^2=10\times10=100$

$10^8=10\times10\times10\times10\times10\times10\times10\times10$

$10^8=100,000,000\ (100\ million)$

Further example

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

Or $(x)(x)(x)$
