The number of different 3 digit numbers that can be formed  =  P(4,3)  = 24

El número de diferentes números de 3 dígitos que se pueden formar = P (4,3) = 24

1 foot = 12 inches.....so...

3.5 ft  * 12    =

(3 + 1/2) * 12  =

3 * 12   +   (1/2) * 12  =

36    +   6 =

42 inches

I didnt have to verify my answer.... ???

Neither prime nor composite

the first positive integer whole number 

If I didn't have to "verify" my answers, it would be just fine......hectictar indicates that we can go back and edit our old posts......I like that.....!!!!

The answer wouldn't be 8p.

2p*4p is the same as 2*p*4*p

First multiply the numbers: 2*4= 8

Then the variables: p*p= p²

Than both products: 8*p²=8p²

Therefore, the answer would be 8p²

I would think the answer would be 8p...

Note....any number of the form  abcdabcd   can be written as

abcd *  10000  +  abcd   =

adcd ( 10000 + 1) =

abcd (10001)

So.....10001 is the greatest common divisor for any number of this form

 √32  = √ (16 *2)  = √16 * √2   =  4√2

 √44  = √{4 * 11} = √4*√11 = 2√11

 √90 = √[9 * 10] = √9 *√10 = 3√10

x^7 =  250000     take the 7th root of both sides

x = (250000)^(1/7)  ≈ 5.903836027749965

k thanks

1 x 8  = 8      the previous two digits multiplied together equal the next term

Yep, snow is beautiful. I love looking up at the skys and seeing it fall down

Just saying there is a big probability that I am wrong, but..

5x4=20

10 cubed =1,000

20x 1,000=20,000

P.S soz if it's wrong

Use PEMDAS (also known as PEDMAS, they stand for the same thing)

Parentheses

Exponents

Division and Multiplication from left to right

Addition and Subtraction from left to right

Using this,

5*4*10^3

5*4*1000

20*1000

20000
 

to get square root on this calculator, type:

sqrt(x)

to get the square root of x

It's 20. I was looking at multiple questions at the same time :D

They are generally called the semi-major axis and the semi-minor axis.

5 x 4 x 10^3  = 5 x 4 x 1000      you can do the multiplication in any order , the result will be the same

20,000   or  2 x 10^4

5x4 is not 9 !!!

5x4x10³ → 20x10³ → 2x10⁴

If you have the axes   it is  pi x axis a  x  axis b

(axes are like 1/2 the two diameters of the ellipse)

radius = 9   area = pi x r^2 = 81pi sq ft

$48.43/ (81 pi)  =  .1903 ~~~ 19 cents per sq ft

Another method: SUbstitute in -3 fo 'x'  and solve for 'k'

k(9) + 6-3 = 0

k(9) = -3

k = -3/9 = -1/3

cosh² - sinh² = 1

cosh x = sqrt(1 + (16/63)²) = sqrt(4225/3969) = 65/63

tanh = sinh/cosh

tanh x = 16/65

coth = 1/tanh,   sech = 1/cosh, csch = 1/sinh 

etc.

We must have:  (x + 3)(kx - a) = 0

So:  kx² + (3k-a)x - 3a = 0. 

Compare term by term with kx² -2x - 3 = 0

Clearly a = 1, so 3k - 1 = -2

3k = -1

k = -1/3
