## anonymous 5 years ago Amistre64 can you help me again?

1. anonymous

$22xe ^{x ^{2}}/\sqrt{e ^{x ^{2}}}$

2. amistre64

ok .... and this is a part of?

3. anonymous

I need to find what it equals. I know what the answer is again, but again do not know how they got it.

4. anonymous

want a screen shot?

5. amistre64

let me see the problem to get an better view of what you need; yes screen shot

6. anonymous

7. amistre64

who is thinking up these things lol

8. anonymous

I told you.,,it's the same guy that thinks he's smarter than me! Telling me I'm wrong all the time!! Humph!

9. amistre64

$\frac{22x.e^{x^2}}{\sqrt{e^{x^2 }}}$

10. amistre64

and you wanna know how they get their answer

11. anonymous

yes

12. anonymous

just index laws

13. amistre64

lets clean it up some: $\frac{22x.b}{\sqrt{b}}$ thats easier to see right? $\frac{22x.b}{\sqrt{b}}*\frac{\sqrt{b}}{\sqrt{b}}=\frac{22x.b.b^{1/2}}{b}$ right?

14. amistre64

does $${b\over b}$$ cancel to 1?

15. amistre64

leaves us: $22x.b^{1/2}$ and we said $$b = e^{x^2}$$ so rewrite it: $22x.e^{(1/2)x^2}$

16. anonymous

yes but l;et me try to catch up...had to go away to give some medicine to my son. Let me scroll up to look at what you've typed.

17. anonymous

You are the best...again thank you! You turned on my light bulb!

18. amistre64

lol...youre welcome
