Question

2,27x9−3,14x9+0,88x9=0,01 решите уравнение

Answer 1

$2,27x^9-3,14x^9+0,88x^9=0,01$
$\frac{227}{100} x^9- \frac{314}{100} x^9+ \frac{88}{100} x^9= \frac{1}{100}$
$\frac{227}{100} x^9- \frac{157}{50} x^9+ \frac{22}{25} x^9= \frac{1}{100}$
$\frac{227x^9-314x^9+88x^9}{100} = \frac{1}{100}$
$\frac{x^9}{100} = \frac{1}{100}$
$x^9=1$
$x=1$
ответ: 1.
