I suppose m, o, d and n are all variables.

then it equals to 1

which is approximately -0.0287267.......

(π x 0.16252 x 3) – (π 0.1592 x 3.12)

= 0.48756π - 0.496704π

= -0.009144π

1000000000000*100000000000000

= 1E12 * 1E14

= 1E(12+14)

= 1E26

which is 100 000 000 000 000 000 000 000 000.

I saw it just right before I saw your msg here

log base 1 of 1 can be any number you like 

It is because:

Let x be the ans of log base 1 of 1

\(log_11=x \)

\(1^x = 1\)

Therefore x takes infinitely many values

There are THREE posted rsponses to this question already.

LOL.

Actually, (8, -4) also works 

63:9  is a ratio.    Be careful, it is NOT a straight division.     EXAMPLE:    63 red marbles  and 9 blue marbles  is a ratio of 63:9    the PERCENTAGE of RED marbles is NOT  63/9    it is  63 out of the TOTAL (72)    or   63/72 x100%          and the BLUE marbles are NOT 9/63   but 9 out of 72    9/72

Let's name (0.2x+0.7y = 8) as (1) and (4x-25= -0.5y) as (2)

From (1),

0.2x = 8 - 0.7y

x = 5(8- .7y) = 40 - 3.5y ------ (3)

Substitute (3) into (2),

4(40 - 3.5y) - 25 = -0.5y

160 - 14y - 25 = -0.5y

135 = 14y - 0.5y = 13.5y

y = 10 ------(4)

Substitute (4) into (1)

0.2x = 8 - (0.7)(10) = 8 - 7 = 1

x = 1(5) = 5

Therefore x=5 , y=10

x^2 + 3xy + (2y)^2 =  x^2  - xy   

2x + y = 12    (1)

The first equation  simplifies to

4xy +  4y^2  = 0     divide both sides by 4

xy  + y^2   = 0     (2)

(1) can be transformed into     y = 12 - 2x

Subbing this into (2), we have

x (12 - 2x) + (12 - 2x)^2  = 0   simplify

12x - 2x^2  +  4x^2 - 48x + 144  = 0

2x^2 - 36x + 144 = 0      divide through by 2

x^2  - 18x + 72  = 0     factor

(x - 6) (x - 12)  = 0

Setting each factor to 0,  x = 6    or  x = 12

When x = 6,  y = 12 -2(6)  = 0

When x = 12, y = 12 - 2(12)  = -12

So.....the solutions are   (6, 0)    and  (12, -12)

These two solutions are verified by WolframAlpha, here :  http://www.wolframalpha.com/input/?i=xy+%2B+y^2+%3D+0+,+2x+%2B+y+%3D+12

Post a specific equation and we'll show you.

Both!  A ratio is a division.

To get the average value, divide by 2pi:

\(average=\frac{\pi (e^2-1)}{2\pi} \rightarrow \frac{1}{2}(e^2-1)\)

.

Thanks a lot!!!!

Like so:

.

\(a^i = {a}^{{-1}^{1/2}} = {a}^{{1/2}^{-1}}=\frac{1}{\sqrt{a}}?\)

That's only what i thinks

It may NOT be real

1/3 * 14000

= 14000/3

LOL.

Let a be the number you started with

multiply by 5 ----- 5a

add 13 ----- 5a + 13

subtract 22 ----- 5a + 13 - 22 = 5a - 9

You end with 5a - 9 and you start with a. LOL.

20 + 3/8

= 160/8 + 3/8

= 163/8

( = 20 3/8)

mod (n)/mod (n) = Error: If you are not sure then use our calculator.

So Good geno!!
