That's what I got and I think that you're just over complicating it!

The answer is 262941862

The part of the question 'stillwater and current' can be interpretted to ways:

1) The current is pushing him in the right direction getting him a time of 2 hours.

 OR

2) The current is pushing against him getting him a time of 4 and a half hours.

I would guess that the question is refering to the view 2. So all you have to do is 18m divided by 2hrs and 18m divided by 4 and a half hrs. Getting 9m/h for still water and 4m/h for fighting against the curent.

You would do 4a+3 times 4a-3 which gets you $${\mathtt{16}}{\mathtt{\,\times\,}}{{\mathtt{a}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{9}}$$ for the fist part!

Then for the secound part $${{\mathtt{4}}}^{{\mathtt{2}}} = {\mathtt{16}}$$, $${{\mathtt{a}}}^{{\mathtt{2}}}$$ is just $${{\mathtt{a}}}^{{\mathtt{2}}}$$ and $${{\mathtt{3}}}^{{\mathtt{2}}} = {\mathtt{9}}$$ so you get the same eqaution as above!

And finally for the last part there is no working out (simplifying) as it's the answer!

All that the equation is doing is showing you how to go from (4a+3)(4a -3) to a more simplified answer.

Ok thanks!

You would do 4 times 5 and 4 times x wich gets you 20 and 4x so your answer is 20+4x

The answer's 20!!!

My proof..

You could also interpret it as (3^5+9)^2 which = 63504 but Melody's is more likely.

Thank you.

P.s Your's is great too

This is not a magic square as:

Row 1: 08+24+01+06+17=56
Row 2: 14+05+16+07+23=65
Row 3: 15+11+22+13+04=65
Row 4: 21+12+03+19+10=65
Row 5: 02+18+09+20+25=74

And that's without taking the colums and diagonals into consideration!

The answer is 6

Yes!! And so can pigs!!!
