0.5=5/10=1/2

0.05=5/100=1/20

0.005=5/1000=1/200

etc. 

Put the decimal over the power of ten that corresponds to the place of the last digit.

0.0005= 5 in the ten thousandths=5/10,000=1/2,000

It won't always be so cut and dry, like=

0.31=31/100=can't be simplified further

Or repeating decimals you probably won't get lke:

0.33 = 1/3

For those, you just have to remember the repeating decimal values of certain fractions, or you can just do the math. 

Let's simplify it:

8^2+2x=11x+4^3

64+2x=11x+64

-64            -64

2x=11x

-2x -2x

0=9x

9  9

0=x

However, you could

just stop at 2x=11x, because there is only one number that works for any equation where Ax=Bx, and that number is always 0.

Ask Siri and get an easter egg. I won't spoil it for you.

Siri also tells you the correct answer. Siri says that it is undefined, which it indeed is. 

You're on a calculator website... come on, use the calculator... just divide it...

There are 1728 (12³) cubic inches in a cubic foot. There are 27 (3³) cubic feet in a cubic yard. There are 3097600

(1760³) cubic yards in a cubic mile. Just put the ratio of linear(not square or cubic) units to a linear unit and cube it. i.e. 12 inches in a foot, 12³  =1728 cubic inches in a cubic foot. 

For square units, ratio².

Hello Guest!

whats the square route of 564536

Since you have a calculator, I recommend this link:

456777=8607/x

Write as fraction

456777x/8607

multiply both sides by x

x=8607/456777

divide both numerator and denominator by 3

x= 2869/152259

Alternative Form

x=0.018842

Solve for x:
6+sqrt(x)=x

Subtract 6 from both sides:
sqrt(x)=x-6

Raise both sides to the power of two:
x=(x-6)^2

Expand out terms of the right hand side:
x=x^2-12 x+36

Subtract x^2-12 x+36 from both sides:
-x^2+13 x-36=0

The left hand side factors into a product with three terms:
-(x-9) (x-4)=0

Multiply both sides by -1:
(x-9) (x-4)=0

Split into two equations:
x-9=0 or x-4=0

Add 9 to both sides:
x=9 or x-4=0

Add 4 to both sides:
x=9 or x=4

6+sqrt(x) ⇒ 6+sqrt(4) = 8
x ⇒ 4 = 4:
So this solution is incorrect

6+sqrt(x) ⇒ 6+sqrt(9) = 9
x ⇒ 9 = 9:
So this solution is correct

The solution is:
Answer: |  x=9

how do you find tan(arccos 2/3) what is it equal to?

tan(arccos 2/3)

= tan 48,1896851

= 1.11803398875

tan(arccos 2/3) = 1.11803398875

Solve for x:
x^2-2 x-8=0

The left hand side factors into a product with two terms:
(x-4) (x+2)=0

Split into two equations:
x-4=0 or x+2=0

Add 4 to both sides:
x=4 or x+2=0

Subtract 2 from both sides:
Answer: |  x=4                 or                    x=-2

Solve for x:
x^2+20 x-150=0

Add 150 to both sides:
x^2+20 x=150

Add 100 to both sides:
x^2+20 x+100=250

Write the left hand side as a square:
(x+10)^2=250

Take the square root of both sides:
x+10=5 sqrt(10) or x+10=-5 sqrt(10)

Subtract 10 from both sides:
x=5 sqrt(10)-10 or x+10=-5 sqrt(10)

Subtract 10 from both sides:
Answer: |  x=5 sqrt(10)-10        or          x=-10-5 sqrt(10)

Hello Guest!

anybody got a clue what x is: {nl} x^2+20x-150=0

{nl} x² + 20x - 150 = 0

p = 20

q = - 150

x_1,2 = - p/2 ±√(p²/4 - q)

x_1,2 = - 10 ±√(100 - (-150))

x_1,2 =  -10 ±√250

x₁ = 5.811

x₂ = - 25.811
