Good work LambLamb,

I got exactly the same answer.

But

are you going to show how you did it? 

Have a look at my "What is Happening?  Wrap#4"

It is the second one in the sticky topics on the bottom right of the screen.

Look at the first row of every post.  :)

You don't believe me?  I am hurt to the bone.

Do you think people from Australia are still chained in the hulls of your convict ships.   That is hilarious :D

Thanks Chris and Alan,

I had not even seen that question :/

I am from Sydney, Australia :)

You didn't confuse me  :)))

I have never heard the term "standard form division" before.

Standard for is just scientific notation.  The English call it standard form and everyone else calls it scientific notation.

I suppose you are refering to

\(5*10^{-4}=\frac{5}{10^4}\)

Am I right in thinking that you are from the UK ?

You have a GREAT icon :))

Well since you asked so nicely :)))

(1.5*10^-10 ) /  (3*10^-7)

1.5/3=0.5    and    \(10^{-10}/10^{-7} = 10^{-10-\; -7}=10^{-3}\)

so

\(\frac{1.5*10^{-10}}{3*10^{-7}}\\~\\=0.5*10^{-3}\\~\\=5*10^{-1}*10^{-3}\\~\\=5*10^{-4} \)

omi, are you going to spoil the game
