Rút gọn: a) 12x^2y^3-10x^2y^3:5x^2y^2+4x(1-3xy)^2 30/08/2021 Bởi Peyton Rút gọn: a) 12x^2y^3-10x^2y^3:5x^2y^2+4x(1-3xy)^2
a) 12x^2y^3-10x^2y^3/5x^2y^2+4x(1-3xy)^2 = (12x²y³ – 10x²y³)/ [ 5x²y² + 4x(1-3x)²] = [ x²y³(12-10)]/ ( 5x²y² + 4x – 24x²y + 36x³y²) = (2x²y³)/[ x(5xy² +4)- 6x²y(4+ 6xy)] Bình luận
a) 12x^2y^3-10x^2y^3/5x^2y^2+4x(1-3xy)^2
= (12x²y³ – 10x²y³)/ [ 5x²y² + 4x(1-3x)²]
= [ x²y³(12-10)]/ ( 5x²y² + 4x – 24x²y + 36x³y²)
= (2x²y³)/[ x(5xy² +4)- 6x²y(4+ 6xy)]
