Maths homework

[M107]

Any help on this one would be most appreciated by my daughter..............last one

Expand the expression;

t

 

[Barx]

Isn't expanding just getting rid of the brackets.

So,

t2 x 4t

could be wrong.

Actually, 4t2

Hi all,

I am a proper dumbo at maths, but, as you have to do the brackets first, [bODMAS and all that!] would t

 

[Phoenix]

4t⁴

EDIT: You can check your answer to a question like this by assuming a value of T and calaculating the original formula and then the new one using the same value

 

[Technician]

No; T to the 4th power plus 3 times T to the fourth power

 

[Andy™]

a school maths question and none of use can answer it...

 

[Theorysparky]

nope, never needed many formulas other than the basic V=IxR etc

thats what I get

t + 3t = 4t brackets first

t

 

[Technician]

When multiplying out brackets the term outside the bracket

must be multiplied by all terms within.

Look at the calculation for temperature coefficients in the OSG.

 

[Theorysparky]

+1

thats how i would answer it

 

[Technician]

A good read; Simon Singh on Fermat's last theorem.

 

[a1]

4t4

 

[M107]

Thanks everybody.

 

[Sidewinder]

The correct answer is:

t

 

[kerching]

what Phoenix, Admin and Reptilian ronald said.....cant fathom 'powers ' on this but in longhand

equation is same as[ t3 x t ] + [ t3 x 3t]

= t4 + 3t4

= 4t4 ....simples [how do you do 'powers' on this??].................... :coat

 

[PC Electrics]

Everyone who got 4t^4 should go to top of class. That's the correct answer

 

[kerching]

Ah.................found it my life is now completen.............. :coat

 

[philbas]

The correct answer is:t

 

[Technician]

Hmmmm....failed to go all the way....story of my life. :|
