sorry hey guys sorry I definitely did not get this up by 6 I tried it and it didn't happen but I will have you guys do your homework quiz at the end of the quiz thing I have to take today I'm if you guys don't get to the homework quiz that's fine you guys can do it on Monday so going over number one  7 time of the second power * 7 to the 4th power all you're going to do you're going to add your turn it's there so it's 7 to the two plus for power which just changes to 7 to the 6 power really anything to like power and above I won't make you multiply out so you can just leave your answer it like that and it 7 to the 6th is fine  number to weave a negative exponent and then we've got a power to a power there's two ways you can do this I think it's easier to multiply him first so I'm going to do G2 the seven-time * -3  which is g to the negative 21 however that negative we've been talking about it for a few weeks now changes it to the reciprocal so now it's 1 /  GE to the 21st power  next one  Doritos 6 to time and then you're going to subtract to your ends because are both the same variable and then they have excellent  so let me rewrite this first so now I have to and to the fourth over  I'm to the 12th which simplifies to to the m 4 - 12  4 - 12 gives you -8  and so that means it pushes the M back down to the bottom so to over and to the 8th power the 8th is not with the two so the 2 does not go down to the bottom just then  number where I first thing I want to deal with is this x to the zero power that just cancels out till 1 and then 5 goes into 24 times and so now I'm going to rewrite it so I know what I'm dealing with I've got one over 4 y to the negative 3 x to the second  when I have a negative on the denominator instead of going more to the bottom cuz there's nowhere else I can go it's going to go back up to the so now this is why to the third over  4X to the second ex does not move because it does not have a negative for the next one we're just taking the four through 4096 one thing that I will let you have on your quiz today is going to be your roots see they should have one Cypress paper that has all the roots on it but the fourth root 4096 is this is 1000 to the 2/3 power on the 1st I think it's easier to write it in radical form  remember you guys to call the index the little dip so three goes in the little dip a thousand goes under the radical sign who is screwing it on the outside I'm so first I'm going to take the cube root of 1000 cube root of 1000 is simply and then 10 square gives you a hundred as your final answer number 8 this one's already in radical form and luckily 81 does have a perfect square so I would just do Square of 81 is 9 to the third power nine to the third power  is 7 turn in 29  then I can see you your final answer Hoops 29  are you guys can go ahead and stop this video here and I'll go ahead and do the next set of problems
