Here's a really good calculator. Re copy and paste the question into the bar, and it'll give you the answer. https://www.desmos.com/scientific or you could use the built in calculator below.

angelcook2007:

it needs to be simplified sorry i didn't mention it in the question

snowflake0531:

wellllll first look at the numbers

snowflake0531:

\[(4xy)(2x^2 y)((3xy)^3)\] that's easeier to read

snowflake0531:

do you know how to simplify 3xy^3?

angelcook2007:

it's 3x ^{3}y^{3} aint it

angelcook2007:

idk how to use the equation thing

angelcook2007:

it's 3x^3y^3

snowflake0531:

use a calculator for now lol, i recommend mathway

angelcook2007:

lol, ok

snowflake0531:

so, it would be 27x^3 y^3

angelcook2007:

im on my school computer so it's blocked

angelcook2007:

lmao

snowflake0531:

ha, yes, school computers block so many things

angelcook2007:

except things that NEED to be blocked

snowflake0531:

anways, so, multiply 4,x,y,2,x,x,y,27,x,x,x,y,y,y lol

snowflake0531:

that's if you expand it

snowflake0531:

but anyways, first muliply the number, it would be 216

snowflake0531:

x would be x^6, and y would be y^5

snowflake0531:

so, \[216x^6 y^5\]

snowflake0531:

i think lol

angelcook2007:

so the answer choice i have it cut down to is 216x^2y^3 and 216x^6y^5

angelcook2007:

oh thanks lol
