for example                          1

                                        ----------     =   1/2

                                             2                                  

first you gotta do * so while you are solving the equation;

2+(2*2) = 2+4 = 6

if you can send the picture i will be able to help

213.5 billion - 199.8 billion =137/10 billion = 13.7 billion

Do you mean

36000*1/10

You can do that on the web2 calc on the home page. :)

10000 more......

To see this, look at the sum of the first five positive even numbers

2 + 4 + 6 + 8 + 10 = 30

And look at the sum of the first five positive odd numbers

1 + 3 + 5 + 7 + 9  = 25

The difference between the two sums is 5.  This leads us to believe that the difference between the sum of the first n positive even numbers and the first n  positive odd numbers is just n.

(5+3)^2

=(8)^2

doesn't make sense!

pi/3=60degrees

draw an equilateral triangle of side length 2

cut it in half.

put angles and side lengths on it

find the height using pythagoras

"read" tan 60 off the triangle.

Multiply the kilometers by  .621  ......that will convert km to miles

I assume we have

tan (x)  = [ 3√3 ] / 3   ???    =

tan(x) = √3

This is just a 60° angle in either quadrant 1 or in quadrant 3 (i.e., 240° )

Let's call the second endpoint (x₁ , y₁)....and by the midpoint formula, we have

(x₁ + 5/3)/2  = 1 + 7/12   and (y₁ + 1 + 2/11)/2 = 4 + 2/3 

And converting 1 + 7/12 to  19/12 and  solving the first equation, we have

(x₁ + 5/3)/2  = 19/12      multiply both sides by 2

x₁ + 5/3  = 38/12      subtract 5/3 from both sides

x₁ = 38/12 - 5/3 = 3/2

And converting 1 + 2/11 to 13/11 and 4 + 2/3 to 14/3  and proceeding as before, we have

(y₁ + 13/11)/2  = 14/3    multiply both sides by 2

(y₁ + 13/11)  = 28/3      subtract 13/11 from each side

(y₁  = 28/3 - 13/11 = 269/33

So, the other endpoint is (3/2, 269/33)

I just realised that I can remove one off the watchlist and then reinstate it and it will  go to the top of the list.

 I did not think that it worked like that before!  I must make use of this feature.    

It does not work that way with the sticky topics.     

$$(3+5)^2=262144^{\frac{1}{3}}$$

You press the button that looks like this 1/x and if you don't want ur numerator to be one then click in front of it and erase it.........

No, because it is divisible by 2

The answer is 4

36c-12d+6d-10c

26c-6d

really look it up online

                    It's the square root of 4. Thats 2 by the just to let you know. :l

In math, you use it to indicate that a number is raised to a power. For example, 2^3 is equal to two to the third power, or 2*2*2, or 8. On the site calculator, you can type it in or use the "x^y" button. 

The square root of a number "n" is a number that when mutiplied by itself returns "n'

The cube root of  number "n" is a number that when multiplied together three times equals "n"

Example

√64 = 8     because 8*8 = 64

³√64 = 4    because 4*4*4 = 64

 The standard form of 308 million is simply:

                                         308,000,000
