Question

Can anyone help solve this crazy equation, please!? 20^3+20^2(20/3)-20(20/3)^2-(20/3)^3

Answer 1

\[20^{3}+20^{2}(20/3)-20(20/3)^{2}-(20/3)^{3}\]

Answer 2

i thought maybe it could be factored but i don't think so
just use order of operations and use a calculator :)

Answer 3

\[[27(8000)+9(8000)-3(8000)-(8000)]/27\]

Answer 4

you can factor 20^3 out of everything

Answer 5

[(8000)(27+9-3-1)]/27

Answer 6

[(8000)(32)]/27

Answer 7

9481.48148

Answer 8

256000/27

Answer 9

9481.481481...................

Answer 10

ok how aare you guys getting these values? where did the 27, 9,3 and 1 come from?

Answer 11

27 is common denominator

Answer 12

how?

Answer 13

it looks like it's 3.

Answer 14

20^3+20^2(20/3)-20(20/3)^2-(20/3)^3
1st term (20^3) = (20^3)/1
2nd term 20^2(20/3) = (20^3)/3
3rd term -20(20/3)^2 = -(20^3)/9
4th term -(20/3)^3 = -(20^3)/27
Now let (20/3) = x
so you have (x/1) + (x/3) - (x/9) - (x/27)
Hope it helps!

Answer 15

Actually, your answer turned on the light bulb, so to speak! I do understand, of course it is very confusing to me, but I get the 27, now I just need to take notes from your post up there and apply it to my work here. Thanks so much! That was great! Don't know what I would have done without the help here!
