Hello there!
Usimov [2.4K]

firstly chain rule is dy/dx = dy/du * du/dx

a) y = 5u² + u - 1 hence dy/du = 10u +1

u = 3x +1 hence du/dx = 3

so dy/dx = 3(10u +1) {sub in u and expand}

b) y= u^-2 hence dy/du = -2u^-3

u=2x+3 hence du/dx = 2

so dy/dx= 2(-2u^-3) {sub in u}

1.) <span>(n+1)n!  = (n+1)!

</span>
<span>2.) (n+8)!/n+8  = (n+8)!/(n+8)
                     =  (n+8)*(n+8-1)! / (n+8)  =  ((n+8)*(n+7)!) / (n+8)
                                     </span><span>Cancel out the (n+8)

3.) 100 x 99 x 98  = (100 x 99 x 98 x 97!) / (97!)  =  (100!) / (97!).

4. (n-1)(n-2)(n-3)  =  <span>((n-1)(n-2)(n-3)</span>(n-4)!) /(n-4)!
                         =   (n-1)! / (n-4)!.

Cheers. That's it.
