Question

How I do rearrange this equation?

Answer 1

My algebra is terrible. I am not too sure to cancel out the ^-2

Answer 2

I would start by naming the constants

-1.564 = a
and
6.9 = b

That makes things a little easier, not having those ugly numbers around. :)

Answer 3

first use the rule :
\[aLn(x)=Ln(x)^{a}\]
then just exponentiate bouth sides

Answer 4

I'm not sure what you mean

Answer 5

My original was to cancel out the ^-2 then divide by -1.564, then take expontial to cancel out the natural log

Answer 6

original idea.

Answer 7

But it's just a mess I know something is wrong.

Answer 8

\[f=[Ln(6,9 \mu/pud)^{-1,564}]^{-2}=Ln(6,9 \mu/pud)^{2*1,564} \]
now:
\[e ^{f} =6,9 \mu/pud^{2*1,564}\]

Answer 9

Thanks guys, really helping a lot!

Answer 10

Ok here it is. Now back to making math videos for me...
