OpenStudy (anonymous):

OpenStudy (anonymous):

OF WHAT?

ganeshie8 (ganeshie8):

wolfram ?

OpenStudy (anonymous):

the numerator is pretty easy , (18+7)^3

OpenStudy (anonymous):

no this a question in worksheet

OpenStudy (anonymous):

BINOMIAL THEOREM

OpenStudy (anonymous):

I will type it again wait

ganeshie8 (ganeshie8):

Okay, denominator is also binomial theorem

OpenStudy (anonymous):

yes how to figure that , out i will post the question in a minute

ganeshie8 (ganeshie8):

3^5 = 243 3^4 = 81 3^3 = 27 3^2 = 9

ganeshie8 (ganeshie8):

thats a pretty pattern to guess

OpenStudy (anonymous):

\[\Large \frac{ 18^3+7^3+2.18.7.25 }{ ?3^6+6.243.2+15.81.4+20.27.8+15.9.16+6.3.32+64 }\] AT last

OpenStudy (anonymous):

Ignore the question mark

OpenStudy (anonymous):

yeah i guesed it (3+2)^6

ganeshie8 (ganeshie8):

looks good!

ganeshie8 (ganeshie8):

but how is numerator (18+7)^3 ?

OpenStudy (anonymous):

thank you

OpenStudy (anonymous):

i added 25

OpenStudy (anonymous):

it was a typo earlier

OpenStudy (anonymous):

so answer is 1 hah

ganeshie8 (ganeshie8):

it still doesn't look right

OpenStudy (anonymous):

oh that is 3

OpenStudy (anonymous):

sorry sorry

ganeshie8 (ganeshie8):

\[ \frac{ 18^3+7^3+3\cdot 18\cdot 7\cdot 25 }{ 3^6+6\cdot 243\cdot 2+15\cdot 81\cdot 4+20\cdot 27\cdot 8+15\cdot 9\cdot 16+6\cdot 3\cdot 32+64 } \] like this ?

ganeshie8 (ganeshie8):

ohk now it makes sense yeah answer is 1 :)
