Question

0,1 Корень из (20) / корень из (45) - 2 ( 17) / (30)

Answer 1

$\frac{0,1 \sqrt{20}}{ \sqrt{45} } -2 \frac{17}{30} = \frac{0,2 \sqrt{5}}{3\sqrt{5} } - \frac{77}{30} = \frac{0,2 }{3 } - \frac{77}{30} = \frac{2 }{30 } - \frac{77}{30} =-\frac{75}{30}=-2,5$

Answer 2

0.1 * sqrt(20) / sqrt(45) - 2 + (17) / (30)

First, we can simplify the square roots: 0.1 * 2.236 / 2.121 - 2 + 0.566 / 30

Now we can perform the multiplications and divisions: 0.2236 / 2.121 - 2 + 0.0188667

Now we can add and subtract: 0.1054 - 2 + 0.0188667 = -1.8757333

So, the final answer is approximately -1.8757333.
