To simplify the given expression.
00:02
Well, even though we have a variable in our exponent term, we can still use our regular exponent rules to simplify this.
00:09
So the first thing i know is that we can, because we're taking this product and raising it to a power, we can use our product of a power rule, meaning i can take this exponent of negative 2 and raise both of these terms to that power.
00:22
So in other words, i'll have 5 being raised to the negative 2 power, and then a to the negative 2x power, also will be raised to the negative 2 power.
00:33
So now let's look at 5 to the negative second.
00:35
This is an example of having a negative exponent.
00:38
Remember, our rule says if we have a to the negative m, it will equal 1 over a to the m.
00:44
So let's apply that to ours...
