This is the same as    37 x 1.739

and there is a calc on the home page.    

ok than thank

oh ok thank you 

It is a very little number so the indice will be negative.

You want just one digit in front of the point so the number part will be    3.456

So you have to JUMP the point over 000 and 3.   That is 4 jumps.  You can actually put the loops in on paper.

So the answer is

$$3.456\times 10^{-4}$$                      

TRY WATCHING THIS CLIP

17 IS a prime number...!!!....thus, it has no other prime factors......

 21 

910

$${\mathtt{2\,300}}{\mathtt{\,\times\,}}{\left({\mathtt{1}}{\mathtt{\,-\,}}{\mathtt{0.011}}\right)}^{{\mathtt{7}}} = {\mathtt{2\,128.638\: \!325\: \!350\: \!214\: \!011\: \!6}}$$

try this: NOTHING!!!

i don't know it yet!!

First thing to do is to draw it.

The path and pool together have an radius of 6m

so together the area is 

$$A=\pi*6^2$$

But for the pool by itself the radius is 5 metres

so the area of just the pool is

$$A=\pi*5^2$$

The area of just the path must be the entire area minus the area of the pool.   

You can finish it.   

The convention is that we assume the positive root, unless we are solving an equation...

So.... √49 = 7

But

x² = 49

x = ±√49 = ± 7

This is a reapeating question but always a good one. :)

Yes I like it too :)

floor [ (2-3x) / (x + 5) ]

This isn't as daunting as it seems

Notice the first few terms....

f(1) = floor( -1 /6) = -1   ..   f(2) = floor (-4/7) = -1... f(3) = floor (-7/8) = -1  ...f(4) = floor (-10/9)= -2

And f(11)  = floor (-31/16) = -2   ....and f(12) = floor (-34 / 17) = -2 and f(13) =floor (-37/18) = -3

And every successive term has has a floor of -3....for example f(1000) = floor(-2998/ 1005) = -3

So.... 3 terms have a floor = -1

And 9 terms have a floor of -2

And (1000 - 12) = (988) terms have a floor of -3

So the sum is   3(-1) + 9(-2) + 988(-3)  = -2985

It is undefined.  You cannot divide by 0

ok there is a lot of confusion here so I will see if I can help to straighten it out for it is quite important.

Firstly  7*7=49     AND    (-7)*(-7)=49

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

Now if the question is  $$\sqrt{49}$$   then the answer is 7     (Just 7 NOT -7)  

This is because if the square root is written into the original question ONLY the positive answer counts.  That is a convention. 

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

However,  if the question is   

$$\\x^2=49 \qquad find\quad x \\\\
$That is different because the square root is not written into the original question.$\\\\
x=\pm\sqrt{47}=\pm7$$

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

Please, if you want to ask questions do so because this is important.

According to  a formula that I found online, we have

t = [ ln (N / N₀) / (-0.693) ]  * 5730      where t is the age of the fossil, N / N₀ is the percent of  C-14 that remains and 5730 is the half-life of C-14....so we have

t = ( ln (.63) / (-0.693)) * 5730 = about 3820 yrs old

$$\frac{\sqrt{84}}{2}}\times\sqrt3\\\\
=\frac{\sqrt{4\times 21}}{2}\times\sqrt3\\\\
=\frac{\sqrt{4}\times \sqrt{21}}{2}\times\sqrt3\\\\
=\frac{2\times \sqrt{21}}{2}\times\sqrt3\\\\
=\sqrt{21}\times\sqrt3\\\\
=\sqrt{7}\times\sqrt3 \sqrt3\\\\
=3\sqrt{7}\\\\$$

Just put this into the onsite calculator.....

Just divide 603.75 by 35    .... this will give you your rate of (something) per hour....
