Ask to simplify the given expression by using our exponent rules.
00:04
Well, the first thing i notice is our outside exponent is negative.
00:08
So remember, to make it positive, we have to take the reciprocal of the base.
00:13
Our base in this case is 2r to the 6m power.
00:16
Therefore, the reciprocal of that will be 1 over 2r to the 6m power.
00:22
And now this will all be raised to the positive third.
00:26
So now we're going to use our quotient power rule for quotions, meaning we have to raise each part of this expression to the third.
00:35
So in other words, for the numerator, i'll have one to the third, and in denominator i'll have two to the third times, then we'll have to raise r to the 6m to the third power...
