Instructions and Help about What Form 8815 Index

Hello and welcome to a video looking at more c1 indices now at c1 it's just as important to be able to evaluate indices but also to be able to rewrite things that we see as part of equations as indices particularly when we are differentiating here I've got just six different examples which i'm going to rewrite as indices instead of what they're what they've given us at the moment so here i've got the square root of x now i could write the square root of x as an indices as x to the power of a half one over x how could I write one over X will that's simply going to be X to the power of negative one one over the square root of x so I know that it's going to be a negative power and it's the square root we saw here that the square root of x is x to the half so this is going to be x to the power of minus one half here we've got two over X this I can write as 2 X to the power of negative 1 this one here five over the square root of x I can write as 5 X to the negative one half and then lastly this one here for over square root of x cubed I can write as for X to the negative negative three halves so as I said at the beginning it's just as important not only to be able to evaluate indices when they have a value but it's just important to be able to rewrite terms in an equation as indices particularly when differentiating
