0,1. căn bậc hai 100 - căn bâc hai 4/25

Lời giải:

\(2 + \frac{1}{6} - x = 10\,\,.\,\,\sqrt {0,01} - \sqrt {\frac{{25}}{{36}}} \)

\(2 + \frac{1}{6} - x = 10\,\,.\,\,0,1 - \frac{5}{6}\)

\(2 + \frac{1}{6} - x = 1 - \frac{5}{6}\)

\(\frac{{13}}{6} - x = \frac{1}{6}\)

\(x = \frac{{13}}{6} - \frac{1}{6}\)

x = 2

Vậy x = 2.
