Question

X^3-25x ×15y:xy+5y
________________
3x-15 ×4x :4

Answer 1

Olá,

$\frac{ {x}^{3} - 25x \times 15y \div xy + 5y }{3x - 15 \times 4x \div 4} =$

Simplificando temos:

$\frac{ {x}^{3} - 25 \times 1 \times 15y \times y + 5y}{3x - 15 \times 1x} = \\ \\ \frac{ {x}^{3} - 375y {}^{2} + 5y }{ - 12x } \\ \\ - \frac{ {x}^{3} - 375y {}^{2} + 5y}{12x}$

Espero ter te ajudado!
