Question

Me ayudan por favor esta bien difícil

Answer 1

Explicación paso a paso:

•••$\frac{ 4{(xy)}^{4} }{ 2{x}^{3} {y}^{2} } + 9x {y}^{2} \\ \frac{2 {(xy)}^{2} }{x} + 9x {y }^{2} \\ 2x {y}^{2} + 9x {y }^{2} \\ 11x {y}^{2}$

•••$\frac{5 {x}^{3}y }{xy} - 3 {x}^{2} \\ 5 {x}^{2} - 3 {x}^{2} \\ 2 {x}^{2}$

•••$7x - 6 > 43 \\ 7x > 49 \\ x > 7 \: \: \: \: \: \\ \: \: x \: pertenece \: a < 7 , \: \: \infty >$

•••${(2b)}^{2} + 8 < 40 \\ 4 {b}^{2} + 8 < 40 \\ 4 {b}^{2} < 32 \\ {b}^{2} < 8 \\ - \sqrt{8} < b < \sqrt{8} \\ b \: pertenece \: a < - \sqrt{8} , \: \: \sqrt{8} >$

•••$3b + 5 < 10b - 6 \\ 11 < 13b \\ \frac{11}{13} < b$
