-16x^-1 y^-3 ------------- 80x^-4 y^-3 Simplify. rewrite the expression with positive exponents.
-16x^-1 y^-3 = - 16 ------------ x y^3 80x^-4 y^-3 = 80 ----------- x^4 y^3 invert the last fraction and multiply = 16 x^4 y^3 ------- * ------- xy^3 80 now simplify and thats it
can you continue with this?
oh - i missed out the '-' before the 16 on last line
I will be honest...I have no clue how to do it from there.
well 16divides into 80 5 times , the y^3's cancel out and x^4 / x = x^3 |dw:1338491936056:dw|
