Thanks mari!

Thanks GoldenLeaf!Now im thinking the answer of ur new riddle!

Hey what about my answer!i told that the colour of the drivers eyes would be the same as the colour of my eyes becoz i was driving the car!

Okay so for the answer we are to tell our eye colour then the answer is " Black" becoz my eyes are of black colour and im driving the car(as ur question says)!

So now is my answer correct riddler!

GCF is the short form of Greatest Common Factor in Maths!

I'm not clear what you are asking here, but it might possibly refer to something like the following:

A composite number can be expressed as the product of a number of primes.  This means the logarithm of that number is the sum of the logarithms of those primes.

For example;  12 = 2*2*3  so log(12) = log(2) + log(2) + log(3)

zegroes , your a grown-up and still you have got those bad habbits of kids!SAD!

Im saying this becoz lying is not a good thing which uve just done!So id advice you to stop lying!

Zegroes , i think we shouldnt forget any of them!i like naruto the same amount i like dragon ball z!but i have to say dragon ball z is more cool!

Hi everone,

Great answers have been provided the last couple of days by CPhill, Rose98, Alan, Rosala, DragonSlayer554, NinjaDevo, Quazars, Zegroes, Kitty<3, Needhelp, GoldenLeaf and Mari379.

Thank all.  

Ninja changed the name of our reference thread to "Reference Material" .  Thanks Ninja, that was smart thinking. 

Now for some interesting threads,

1) I like questions like this   (Thanks CPhill )

1/17=17*1/(17^2)

$$\begin{array}{rll}
0.05^{1/n}&=&0.8609\\\\
log(0.05^{1/n})&=&log0.8609\\\\
(1/n)log(0.05)&=&log0.8609\\\\
n&=&\frac{log0.05}{log0.8609}
\end{array}$$

$${\frac{{log}_{10}\left({\mathtt{0.05}}\right)}{{log}_{10}\left({\mathtt{0.860\: \!9}}\right)}} = {\mathtt{20.001\: \!293\: \!705\: \!215\: \!387\: \!9}}$$

This is a difference of 2 squares question.

(x+5)(x-5)=x²-5² = x²-25

Is this the question Nataszaa

cubed sqrt128x^7

$$(\sqrt{128}x^7)^3\\\\
=(8\sqrt{2}x^7)^3\\\\
=512\times2\sqrt{2}x^{21}\\\\
=512\times2\sqrt{2}x^{21}\\\\
=1024\sqrt{2}x^{21}\\\\$$

Well mari379, don't you have the date displayed on your computer or phone?

Also, every post has got a date stamp on it.

Also,  When you asked, it was the 14th for many people but the 15th for me.

So someone could have answered you corectly from their perspective but it would be incorrect from your perspective.

The trials and tribulations of being on an international forum!  

The value of 4 is 4

$$\frac {48+\frac{(2-1)}{7}+50+(2-2)}{2}-\sqrt{4}+50\\\\
=\frac {48+\frac{1}{7}+50+(0)}{2}-2+50\\\\
=\frac {48+\frac{1}{7}+50}{2}-2+50\\\\
=\frac {98+\frac{1}{7}}{2}-2+50\\\\$$

$${\frac{\left({\mathtt{98}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{7}}}}\right)}{{\mathtt{2}}}}{\mathtt{\,-\,}}{\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{50}} = {\frac{{\mathtt{1\,359}}}{{\mathtt{14}}}} = {\mathtt{97.071\: \!428\: \!571\: \!428\: \!571\: \!4}}$$

Umm different answer from zegroes - lets try the site calc.

$$\left({\mathtt{48}}{\mathtt{\,\small\textbf+\,}}{\frac{\left({\mathtt{2}}{\mathtt{\,-\,}}{\mathtt{1}}\right)}{{\mathtt{7}}}}{\mathtt{\,\small\textbf+\,}}{\frac{\left({\mathtt{50}}{\mathtt{\,\small\textbf+\,}}\left({\mathtt{2}}{\mathtt{\,-\,}}{\mathtt{2}}\right)\right)}{{\mathtt{2}}}}{\mathtt{\,-\,}}{\sqrt{{\mathtt{4}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{50}}\right) = {\frac{{\mathtt{848}}}{{\mathtt{7}}}} = {\mathtt{121.142\: \!857\: \!142\: \!857\: \!142\: \!9}}$$

ok lots of different answers happening here.  One of the reasons is that there is a bracket missing in the questions and it keeps getting interpreted differently.

Fix up the bracket and we will fix up our anwers.    

Thanks Ninja,

I would have just said

$$\dfrac{26\frac{1}{3}-8\frac{1}{4}}{2}$$

$${\frac{\left(\left({\mathtt{26}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right){\mathtt{\,-\,}}\left({\mathtt{8}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right)\right)}{{\mathtt{2}}}} = {\frac{{\mathtt{217}}}{{\mathtt{24}}}} = {\mathtt{9.041\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

$${\mathtt{217}} \,{mod}\, {\mathtt{24}} = {\mathtt{1}}$$   

 (I just wanted to try out the mod function on the calcuator - I haven't used it before  

Answer = 9 and 1/24 inches

You cannot take sin inverse 5 because that means 

$$sin\theta=\frac{5}{1}=\frac{opposite}{hypotenuse}$$

but the hypotenuse has to be the longest side so this doesn't make sense!

Hence,

    $$\\So\;\; sin^{-1}x \;\;\mbox{Only exists for }-1\le x\le1\\
\mbox{This is also true for } cos^{-1}x\\\\$$

But

$$tan\theta = \frac{opp}{adj}$$

Either one of these can be the biggest one so of course you can take  $$tan^{-1}5$$   That is perfectly fine.
