Question

how do i simplify (2y^2x^3h)^2

Answer 1

(2y^2x^3h)^2 is the same as:
(2y^2x^3h)*(2y^2x^3h)
then you times everything on the left by everything on the right like so:
2y*2y = 4y, 2y*2x = 4yx, 2y*3h = 6yh
so far, we now have 4y+4yx+6yh
then we go do the same for the rest:
2x*2y = 4xy, 2x*2x = 4x, 2x*3h = 6xh
so now we combine like terms, and add up those equations:
4y+4yx+6yh+4xy+4x+6xh
now we do the same for the last bit:
3h*2y = 6hy, 3h*2x = 6hx, 3h*3h = 9h
now we combine the like terms again, which there is no more:
4y + 4yx + 6th + 4xy + 4x + 6xh + 6hy + 6hx + 9h is now the most simplified form i believe

Answer 2

oops, not 6th, its 6yh, damn autocorrect
