Question

2/3a (3/5 + 4/3 ab) (5/4 - b) =

Answer 1

Respuesta:

$=\frac{2a(20ab+9)}{9(4-b)}$

Explicación paso a paso:

$=\frac{2}{3}a(\frac{3}{5}+\frac{4}{3}ab)\frac{5}{4-b}\\ \\ =\frac{2}{3}a\frac{5}{-b+4}(\frac{4ab}{3}+\frac{3}{5})\\ \\=\frac{2(x)5a(\frac{3}{5}+\frac{4ab}{3})}{3(4-b)}\\\\ =\frac{10a(\frac{ab}{3}+\frac{3}{5})}{3(-b+4)}\\\\ =\frac{10a\frac{20ab+9}{15} }{3(-b+4)}\\ \\=\frac{\frac{2a(20ab+9)}{3} }{3(-b+4)}\\\\ =\frac{2a(20ab+9)}{3(x)3(4-b)}\\ \\=\frac{2a(20ab+9)}{9(4-b)}$
