1.496 x 10^11 m = 1 Astronomical Unit

1.496 x 1.7 x 10^11 / (3 x 10^8)  x  1 min/60 sec = 14.13  minutes

Seventeen.

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

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

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

x sqrt 3 =6  ?

Divide both sides by sqrt 3

x=  6  /  sqrt 3

x= 6 sqrt 3 /3

x= 2 sqrt 3

x = 3.464

Recall that    e= mc^2

e= 4.36 x 10^?   x  (3x10^8 m/s)^2     Sorry....your question got garbled in posting....I do not know what your numbers are!

Hmmmmm...  Have not heard of that one !

90   prime fact  = 3 x 5 x 2 x3           cube root of 90 =4.48       Well , that didn't help

27  prime fact = 3 x 3 x 3                    Cube root of 27 = 3        It worked for that!   Probably not the BEST though.

For finding cube roots, the best way is a calulator !!!!
