5*10^(3)=5*10^3 = 5000
The bracket is meaningless
The unit would be metre seconds but I cannot think why this would ever be useful !
I want to help you understand Braksess but the setting out is defeating me.
first a neg div by a neg is pos so just forget the signs.
Maybe this will help

I am really sorry that we did not get to your question we juust have too many questions to get through them all but it is really good that you did it yourself.
Are you happy with you answer?
$${\left({\frac{{\mathtt{5}}{!}}{{\mathtt{3}}{!}{\mathtt{\,\times\,}}({\mathtt{5}}{\mathtt{\,-\,}}{\mathtt{3}}){!}}}\right)} = {\mathtt{10}}$$ YES i Just tried it to check
Yes I would do it the same as anon - Thank you anon
thank you to both of you.
Just a small careless error first anon.
Your diagrams are great. Thanks
r varies directly with s. If r = 9 when s = 3/2,find r when s = 1.
$$\\r\;\alpha \;s\\ r=k \;s\\ Find\;k\\ 9=k*3/2\\ 9*2/3=k\\ k=6\\ so\\ r=6s\\\\ When\;s=1\\ r=6*1\\ r=6$$
Put it in the web 2 calc like this
[2nd] [atan](1.11)
Make sure the calc is set to degrees (or radians)
On other calcs it may be tan-1(1.11)
Inverse tan is the same as arc tan.
$$\\\theta = 30 degrees\\\\ 180\;degrees = \pi\; radians\qquad $This is something you need to know$\\ so\\ 1 \;degree = \frac{\pi}{180}\;radians\\ so\\ 30\;degrees=30\times\frac{\pi}{180}\;radians\\\\ 30\;degrees=\frac{\pi}{6}\;radians\\$$
Does that answer your question ?
