Is this what you mean?

what is (x^ 2/3)^ 4/5, if yes then,

x^8/405

a times .0675 + a = 105 what is a

a = 6000/61

what is the mean of this set of numbers: 20 17 19 22 18 17 5 without the outlier

20+17+19+22+18+17=113/6=18.83 The mean without the outlier.

CPhill Or Alan: Please verify this.

Approx. 3.1415926

Ikr! XD

7x-x-=455,

6x=455

x=455/6=75.83333....etc.

what is 7.5x10^3/1000?

=7.5

Car A has a head start of   10 seconds/3600  (65km/hr)

Car A position is     10/3600 (65) + 65 t

Car B position is      70 t

WHen they are equal, car B will be caught up to Car A

10/3600 (65) + 65 t  =  70 t

650/3600 = 5 t

t =130/3600 of an hour    or   130 seconds

Checking:    Car A  Position after 130 seconds (+ 10 second head start) = 140/3600 (65km/hr) = 2.527 km from 'start line'

                     Car B position after 130 seconds                                          =  130/3600 (70km/hr) = 2.527 km from 'start line'

SORRY....  I had wrong speed value for car B in my original submission......!

WHen they are equal, car B will be caught up to Car A

Checking:    Car A  Position after 65 seconds (+ 10 second head start) =  75/3600 (65km/hr) = 1.354 km from 'start line'

1. You can write it like this: 7,776.20, or as fraction:38,881/5

7+4e

250/31/3=250 X (3/10)=750/10=75

About 5 orders of magnitude, or more precisely: 4.76 orders of magnitude.

What is 0.00000394 estimated as the product of a single digit and a power of 10?

3.94 X 10^-6=4 X 10^-6 approx.

Just divide it by a 1000:

2500/1000=2.5kj

40.18 /  796  = about  5%

what is the % of 40.18 out of 796. ?

I am budgeted 796. labor hours a week what % of that is 40.18 hrs?

Just divide 40.18/796=.0505 X 100=5.05%

e^(-t)=0.01   take the ln   of both sides

ln e^(-t)=  ln(0.01)     and by a log property, we can write

(-t) ln e  = ln (0.01)     and ln e  = 1, so we can forget this term

-t = ln (0.01)    multiply both sides by  -1

t = -ln(0.01) =  about 4.605

Algebraically, this is the solution:

v = ±sqrt(13/3)

Graphically, this is how you plot it:

Plot[{-5 + v^2, 8 - 2 v^2}, {v, -4.16333, 4.16333}]

I guess you want to evaluate  x^2 + 6x + 9   when x = -4   ???

So we have

(-4)^2 + 6(-4) + 9   =

16 - 24 + 9  =

25 - 24  =

1

In scientific notation, it's

5.8 x  10¹⁰    

 But  since 5.8 is close to 6 and you want an estimate, we can write....   ≈ 6 x 10¹⁰        

Your answer is: 1.48 X 10^-9 meters

can somone help me put these in scientific notation\

43,000 =4.3 X 10^4

0.0072=7.2 X 10^-3

0.000091=9.1 X 10-5

2.38656 x 10⁷
