## drpeppergal Group Title Can someone refresh my mind on how powers work? Such as 10 to the -4th power 2 years ago 2 years ago

1. lgbasallote

$\huge a^{-m} \implies \frac 1{a^m}$ does that help?

2. lgbasallote

$\LARGE 10^{-4} \implies \frac 1{10^4} \implies \frac 1{10 \times 10 \times 10 \times 10}$
