Question

How would the sum of cubes formula be used to factor x3y3 + 343? EXPLAIN THE PROCESS. Do not write the factorization.

Answer 1

there is 343 or the last 3 is exponent ?

Answer 2

its x^3*y^3 +343

Answer 3

i think thats what you asked idk...

Answer 4

so than you need check than the number 343 is a perfect cube number for what you need calcule cuberoot(343)= ?

Answer 5

and the cuberoot of 343 is 7.

Answer 6

Right; it is. So, given the expression (xy)^3 + 343, how would you factor this? Note that you are to discuss how you'd factor here, not to do the actual factoring (but you could do that also, on the side, to get a feel for what you need to explain in writing).
