Amaral and the dogs

[Mr Gray]

Ding gong.

You both got it wrong.

no Jack got it right...then he got the next more difficult one right whose answer was 22...but that took a little longer

[Mr Gray]

I don't think wind and rain were a problem for Eddie;

The dog will locate human cadaver in water either from the bank side or when

deployed in a boat where a large area may be covered using a gridding system.

the wind and the rain would be problem as they would dissipate the residual scent...in the case of a cadaver it would not be a problem as we are not dealing with residual scent

No dave.

Log to the base 4 of (1/8) = - 1.5.

Not -2/3.

If it helps , just try   ( log 0.125 ) / ( log 4 ) = -3/2 or -1.5.

Not -2/3.

If it helps , just try   ( log 0.125 ) / ( log 4 )

yes the answer was 4 and Jack got it right...is that the tenth time I've told you that

[stephen25000]

yes the answer was 4 and Jack got it right...is that the tenth time I've told you that

but it's wrong dave.

Try it on a calculator.


THE ANSWER IS not  -2/3.

yes I did that when I was about 15...nearly 50 yrs ago...so it's a bit rusty now...like my eldest son could play both those two really fiddley bits in the middle of Fur Elise when he was 10...but he couldn't play them now...

perhaps we could do 20 pages on my eldest son...more relevant really as he studied medicine at Leicester where Gerry lectured

[Mr Gray]

but it's wrong dave.

oh you are confused... I misquoted the question slightly...didn't expect the Portuguese inquisition...nobody does...but the answer was x=4...and Jack worked it out

You didn't misquote.

You and your son got it wrong.

[Mr Gray]

You didn't misquote.

stop acting like a duck....the whole point is that Jack got the answer right...x=4...without doing the calculation...when I posed the question I put logx(I/8)=-2/3 instead of -3/2.....but jack worked it out

9 year olds are not taught logs in schools.

It's about time you stopped telling stories.

You get caught out.

That is a "D" in the thread title, not an "L"
It says "Amaral and the Dogs"

he didn't need to understand logs to find the answer

yes I know ..what I am pointing out is that things that might seem impossible may have a really simple explanation...I actually think that's extremely relevant

[pegasus]

You don't need logarithms to do 1.416...+21.25
Sometimes finding the answer is as easy as adding.

[Mr Gray]

You don't need logarithms to do 1.416...+21.25
It's elementary decimal addition.

at least its stopped Stephen quoting totally irrelevant chemistry for the last couple of hours
