Thanks Chris :))

Nice work chris,  Your diagram looks good :)

Thanks Sir-Emo-Chappington and CPhill,

This question looks really interesting :))

It is not a diaphantine equation.

No one said that the answers had to be integers.

That is not correct anon :(

What shape is it?  Is is a sphere (ball shaped)?  Do you mean surface area?

$${\sqrt{{\frac{{\mathtt{17\,000\,000\,000}}}{\left({\mathtt{37.1}}{\mathtt{\,\times\,}}{\mathtt{1.12}}\right)}}}} = {\mathtt{20\,226.861\: \!212\: \!673\: \!36}}$$

100*100=10000

so sqrt(10000)=100

Solve each equation. Check your answer. |-4x|=32 

 $$\small{
\begin{array}{rcll}
|-4x| & = & 32 &\qquad \text{(square both sides)}\\
( |-4x| )^2 & = & 32^2 \\
(-4)^2\cdot x^2 &=& 32^2 & \qquad \text{(remove brackets)}\\
4^2 \cdot x^2 &=& 32^2 \\
4^2 \cdot x^2 - 32^2 &=& 0\\
(4x-32)\cdot(4x+32) &=& 0\\
\end{array}$$

(1) 4x-32 = 0  -> 4x = 32 ->  x = 32/4 -> x = 8

(2) 4x+32= 0  -> 4x=-32 ->  x = -32/4 -> x = -8

(1) | -4 * 8 | = |-32| = 32 ( okay )

(2) | -4*(-8) | = | 32 | = 32 ( okay )

$$x \times x^2y=x^3y$$

$$\sqrt[4]{625}=\sqrt[4]{25*25}=\sqrt[4]{5*5*5*5}=5$$

or

$$\sqrt[4]{625}=625^{1/4}$$

625^(1/4) =    $${{\mathtt{625}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right)} = {\mathtt{5}}$$

Hi,

I am sorry but no one who uses this forum has anything to do with the coding.

I will however message admin and include the address of this post.

I am sorry that I cannot be more help :(

Yes, it is perfect, thanks anon :)

Thanks anon,  

Here is another way

$$\\-24-\frac{p}{8}=\frac{3p}{8}\\\\
-24-\frac{1p}{8}+\frac{1p}{8}=\frac{3p}{8}+\frac{1p}{8}\\\\
-24=\frac{4p}{8}\\\\
-24=\frac{p}{2}\\\\
-48=p\\\\
p=-48$$

I do not understand the question :(

Neither do I.

BUT I am confused, what is it that we don't understand?

Hallo anonymous!

5c - 4 - 2c + 1 = 8c + 2                      both sides : - 8c + 4 - 1

5c - 2c - 8c = 2 + 4 - 1

- 5c = 5                                              both sides :  / ( - 5 )

c = - 1

Hallo anonymous!

solve 3x^2-8x-11=0

3 x² - 8 x - 11 = 0                    [ / 3

x² (- 8 / 3) x (- 11 / 3) = 0

p = - 8 / 3      q = - 11 / 3

x(1;2) = - p / 2 ±√ ((p / 2)² - q)

x(1;2) = 4 / 3 ±√ ((4 / 3)² + 11 / 3)

x(1;2) = 4 / 3 ±√ (16 / 9 + 33 / 9) = 4 / 3 ±√ (49 /9) = 4 / 3 ± 7 / 3

x1 = 11/3 = 3  2/3

x2 = - 3/3 = - 1

x1 = 3 2/3

x2 = - 1

test:

3 x² - 8 x - 11 = 0

3*(11/3)²-8*(11/3)-11=0

0=0     okey

3*(-1)²-8*(-1)-11=0

0=0     okey

:- )

start by adding 1/8 because remember anytime a number move to the other side of the equal sign it changes its sign

so -24-1/8p=3/8p

         +1/8p=1/8p

-24=4/8p divide on both side 4/8

so the answer is p=-48

and to check the answer you multiply -48*4/8 which will equal -24.

so check 4/8(-48)=-24

you can check it on the scientific calculator

4x^2y(5xyz) is solved by

20x^3y^2z

just multiply the 4 and 5

then x squared and x

y and y

and z stands alone

hope it's right

3k - 1 = 7+2  ..... simplify the right side

3k -1  =   9       now....add 1 to both sides  so that we can have just 3k on the left side

     +1    +1

3k = 10     divide both sides by 3

k  = 10 / 3       and that's it  !!!

Log 5/36 - Log 5/9 = -log 4 ....  and we can write....

log [(5/36) / (5/9)] =

log [ (5/36) ( 9/5) ] =

log (9 / 36)  =

log ( 1 /4)  =

log 4^-1  =

(-1)log 4)  =

-log 4

6.7x = 5.2x + 12.3     subtract  5.2x from both sides

1.5x = 12.3     divide both sides by 1.5

x = 8.2
