Electricians should know there basic maths.....DO YOU!!!!

[Octopus]

Just gave it to my 12 year old daughter who came up with 20 in about 1 min

Who has just said she couldn't believe who many wrong answers there were!

Your answers were some of the more exotic out there... the norm is either 20 or 320... well i hope i have given a valuable lesson in maths today and you know what they say 'Everydays a school day' .... now stick a thanks on my post for showing you your daughter is better at basic maths than you :iamwithstupid:
lol

My calculator worked this out so does this mean I'm still an electrician? Dark wood calculate this easy equation and give me the answer (6^x+6^-x)/6 until then I will resume the role as most powerful electrician.

It's 20.

Brackets, indices, division, multiplication, addition, subtraction.

Edit: Just read through whole thread and the answer's already been blimmin' revealed! Now I don't feel so clever

I get 12 if ive read the sum correctly i assume ^ denotes squared
i get zero if the x value is the multiplier to be used on 6

You set 6^x where x isn't a multiply sign but a unknown value but regardless of what it is the sum within the brackets will cancel itself out leaving 0/6 =0

The x within the brackets can't be a multiply sign as it wouldn't make mathematical sense if it was so you have actually thrown up a sum that can be easily worked out.

Are you answering the original post or the recent post by Ducksy.... the answer to original post is given as 20 and the reason why in my previous posts

So would that be

(6 squared multiply by X + 6 squared minus X) divide by 6

X being an unknown value without having the answer?

No as you have written it the 'x' is the value you ^ points to i.e. 6^2 =6squared or 6^5 = 6 to the power of 5 or 6x6x6x6x6

Ahh I'm with you now. I'll just go for a lay down now my head hurts.

Accidental equation or not you are not the most powerful Electrician you were hoping :smug:

 

[Silly Sausage]

calculate this easy equation and give me the answer (6^x+6^-x)/6

f(x) = (6[SUP]x[/SUP] + 6[SUP]-x[/SUP])/6

x=0, f(x) = 1/3

as x increases,
f(x) rapidly tends to 6[SUP](x-1)[/SUP]



Next...

 

[ian.settle1]

f(x) = (6[SUP]x[/SUP] + 6[SUP]-x[/SUP])/6

x=0, f(x) = 1/3

as x increases,
f(x) rapidly tends to 6[SUP](x-1)[/SUP]
