SOLUTION: I need to simplify these but can't figure it out. I'm awful at math. Thanks for any help.
a. y^3 (10x^2 + 3y-1) (5x^3 - 3xy - y)
b. (a^2 + 2b)(5a^3 - 3b^-3/2 - 1)/b

Question 64934: I need to simplify these but can't figure it out. I'm awful at math. Thanks for any help.
a. y^3 (10x^2 + 3y-1) (5x^3 - 3xy - y)
b. (a^2 + 2b)(5a^3 - 3b^-3/2 - 1)/b^-2
Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
Y^3(10X^2+3Y-1)(5X^3-3XY-Y) FIRST WE MULTIPLY BOTH TERMS ( )( ) BY Y^3 THUS
(10X^2Y^3+3Y^4-Y^3)(5X^3Y^3-3XY^4-Y^4) NOW MULTIPLY THESE TWO TERMS THUS
(5X^3Y^3-3XY^4-Y^4)
---------------------------------------
50X^5Y^6+15X^3Y^7-5X^3Y^6
*********-30X^3Y^7-9XY^8+3XY^7
******************-10X^2Y^7-3Y^8+Y^7
-------------------------------------------------------
50X^5Y^6-15X^3Y^7-5X^3Y^6-9XY^8+3XY^7-10X^2Y^7-3Y^8+Y^7
