Question

2/7 x 3/2^4 ( - 2) x 3^2

Answer 1

Respuesta:

Explicación:

$=\frac{2}{7}\\ \\=\frac{2}{7}\cdot \frac{3}{2^4}\left(-2\right)x^{1+1}\cdot \:3^2\\=\frac{2}{7}\cdot \frac{3}{2^4}\left(-2\right)x^2\cdot \:3^2\\=-\frac{2}{7}\cdot \frac{3}{2^4}\cdot \:2x^2\cdot \:3^2\\=-\frac{2\cdot \:3\cdot \:2x^2\cdot \:3^2}{7\cdot \:2^4}\\-\frac{3^2\cdot \:12x^2}{2^4\cdot \:7}\\=\frac{2^2\cdot \:3^2\cdot \:3x^2}{2^4\cdot \:7}\\=\frac{3^3x^2}{2^2\cdot \:7}\\-\frac{3^3x^2}{2^2\cdot \:7}\\-\frac{27x^2}{2^2\cdot \:7}\\2^2\cdot \:7=28\\2^2\cdot \:7\\28\\=-\frac{27x^2}{28}$
