(1+r)=(1+0.17/12)^12

$${\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{0.17}}}{{\mathtt{12}}}}\right)}^{{\mathtt{12}}}{\mathtt{\,-\,}}{\mathtt{1}} = {\mathtt{0.183\: \!891\: \!728\: \!240\: \!085\: \!4}}$$

I was not referring to Rosala's outer beauty although i am sure she is very pretty.

I was referring to her inner beauty!   

Rosala has a beautiful personality.

I also really liked your poem Rosala!

Another excellent explanation pokemonfan58.  

Have you googled it yet?

That is always a good place to start.

I haven't actually heard of it.

Ninja has answered correctly but I think that perhaps you mean 

0.15²*100

I went to the format drop down menu and choose superscript to write this but this is an easider way,

0.15^2*100    The hat means 'to the power of'

Now if this is what you meant you can go straight to the site calc on the home page to get an answer. OR

15squared=225

so 0.15*0.15=0.0225

0.0225*100=2.25

No one has answered you because we do not understand what you are asking  

I'm sorry, I did a number line before I opened the question so I didn't realise that you had already done one Ninja.

I can't bear to let mine go to wast so here it is.

On number lines the bigger number is always on the right.

Like 2 is bigger than 1

So here you can see that -0.8 is bigger than -1.4

----------------------

I'll have to take a look at what Ninja used for his numberline.  I agree it is a good one!  Thanks for the info and thumbs up from me.  

Maybe you could add it, with a covering blurb, to your information pages etc thread

I did mine with GeoGebra.

-----------------------

This is not a question.  It is a statement.  If you graphed it it would be a line.

The y intercept would be 4 and the gradient is -1/2

Maybe there was more to this questions?   

    What a great effort pokemonfan58!

I rarely double up on CPhill's points.  I only do that for extra special answers.

I am doing it here for you.  Good work!
