Amistre64 can you help me again?

Question

anonymous · Answer

amistre64 · Answer

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

anonymous · Answer

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

anonymous · Answer

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

amistre64 · Answer

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

amistre64 · Answer

and you wanna know how they get their answer

anonymous · Answer

yes

anonymous · Answer

just index laws

amistre64 · Answer

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?

amistre64 · Answer

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

amistre64 · Answer

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