Answer 1

can you help from (d)

Answer 2

can't you just multiply together and then take derivative?

Answer 3

yeah you can even do that! :)

Answer 4

this is easier than c in my opinion lol

Answer 5

Yeah @babalooo is right.

Simplify it @LilySwan - Can you do that?

Answer 6

i know we have to ue the product rule but at one point i think im messing up so im stucked

Answer 7

You are given with :

\(y = [50x^4] [20x^8] \)

Right?

Answer 8

yes

Answer 9

Ganeshie showed you this, just multiply and use power rule.

Answer 10

Now, instead of using product rule and making it more complicated. We will follow some basics. We will simplify it a bit.

Answer 11

@LilySwan - Ganeshie8 explained you this. Do you want more help? Or did you net get what Ganeshie8 explained?

Answer 12

*not.

Answer 13

\[d/dx(y) = [4(50x^3)][8(20x^7)]\]

Answer 14

Remember that great table he made for you? Use the product rule.

Answer 15

Well first multiply it as you normally would, as mathslover requested you should simplify it before taking the derivative.

Answer 16

i just told that i tried simplifying it but got stuck

Answer 17

Okay, show us what you did yet. We will try to help you then.

Answer 18

I mean, act if you're not going to take the derivative, what would you do if that problem said simplify?

Answer 19

\[50x^4*20x^8 =?\]

Answer 20

\[ax^n \times bx^m = (a \times b)^{n+m}\]

Answer 21

With that said your answer will be?

Answer 22

1000x^12

Answer 23

Correct, simple right? Now use the power rule.

Answer 24

12000^11

Answer 25

so we should simply be using a power rule here

Answer 26

That's it, that was the power rule.

Answer 27

can you help with (e)

Answer 28

Use the quotient rule

Answer 29

in the quotient we be using power rule first

Answer 30

You should go back to ganeshies table, and take a screen shot or write down all the rules, and then you can see how to approach each problem.
