Find the greatest common factor of the numerator and denominator, and divide the two by the GCF.

Letters or symbols that take the place of numbers. 

Example: x+1=3

x=2 because 2+1=3.

Um... 1? 

You can't simplify 3/4 any further.

10 / √181      =  {rationalize the denomonator}

[10√181] / 181

1x * (-1 x^3) =

(1)(-1) * (x)(x^3) =

-1x^4

This is no math Q. It's a life Q. Life is a test till death made God to see if you are wathy of goning to hevan.

50/√10 + 20/√10  =   { we have like denominators, so just add like "normal" fractions }

[50 + 20] / √10  =

70 / √10

Sa  = 4*pi *r^2   ....so

618 = 4 * pi *r^2       divide both sides by 4 pi

618/ (4 pi) = r^2       take the positive root of both sides

r = about 7.013 cm

Scientific notation, it means that the result is insanly big and therefore, the calculador simplifies it

2.56e+2 = 256

3.5647e+4= 35647

This is equal to

2.56*10^2

So what your calculator is actually saying is

3.7199333*10^41

Which equals

371993330000000000000000000000000000000000

Here you go.........

If you mean when we multiply, the answer is no.......we only need equal denominators when we add or subtract

136 x 6   will give you your answer  (in cubic feet)

[(1939.20) +  (-213.76)] / 2   =   862.72

P(x) = (x -4)^2 (x +3)  =  x^3  - 5x^2 - 8x + 48

If the y intercept = -19.2  we need to solve   48m = -19.2      and m = (-2/5)...so....

P(x) = m ( x^3  - 5x^2 - 8x + 48) =  (-2/5)x^3 + 2x^2 + (16/5)x - 19.2

P(x) = (x+3)(x - 1) (x - 6)  = x^3 - 4x^2 - 15x + 18

So....to have a coefficient of -12 on the x^2 term, we need  this

P(x) = (3) [ x^3 - 4x^2 - 15x + 18]  =  3x^3 - 12x^2 - 45x + 54

(x-2)^2 (x+5)^3 (x-5)

The zeroes are the x values that make each thing in the respective parentheses  = 0

So ... we have  x = 2, x= -5 and x = 5

.75 = (1/2)(1 - cosΘ)    multiply both sides by 2

1.5 = 1 - cosΘ    rearrange

cosΘ  = 1 - 1.5   = -.5

And using the cosine inverse, we have

cos-1(-.5) = 120°, 240°

9, since 9 is the highest power in the polynomial.

We have 15 employees....and we wnat to choose any three of them....this can be done in

C(15, 3)   = 455 different ways

But...once chosen.....we have 3! ways to assign the jobs to the three employees....so

455 x 6 = 2730 ways

Just type sin(4) on any calculator to find out.

Putting x^2 will give you $${{\mathtt{x}}}^{{\mathtt{2}}}$$. On Windows computers, to type ^, hold Shift and press 6 at the same time.
