Hello Folks,
I need to re-arrange this formula and im not sure if i am going about it the right way, can someone please help me.
My first thing to do would be to multiply both sides by 1000 and then multiply both sides by T.
Is this correct, do i treat the (4.302 x 10^-3) as a single entity?
so the result would be
T = 4.302 x 10^-3 x 1000
Thanks.
Edit: Is 4.302 x 10^-3 a single entity as it is standard form?
and should i work it out in my calculator like
1000 x (4.302 x 10^-3)??
Thanks again
at the risk of sounding like a complete idiot, well theres no risk, i do. I dont understand your answer, a proportionate?
I'm sorry, I've not done maths in a long while and this has kinda been sprung on me.
Your solution seems a lot different to mine, could you explain it?
I was more wondering if i had A technique, even tho it may not necessarily be the best.
thank you.
You had exactly the same thing as I did. I just went after it a bit differently. A proportion is simply two fractions that are equivalent to each other.
If , then
In your last step you had 1000 x (4.302 x 10^-3).
That's the same as my first step with a little arranging. All these terms are factors, so you can move them around all you like. For example abc=cba=bca=acb = and so on. I did change the 1000 to 10^3 so you could see how it reacted when we multiplied by 10^-3.
10^3 times 10^-3 = 10^0 because you add the exponents. And 10^0 is the same as 1. So, in essence, you are multiplying 4.302 by 1.
