Question

помогите пожалуйста ​

Answer 1

Ответ:

Объяснение:

а)

$0.5\sqrt{0.04} +\frac{1}{6} \sqrt{144} = 0.5\sqrt{0.2*0.2} +\frac{1}{6} \sqrt{12*12} = 0.5|0.2| +\frac{1}{6} |12| = 0.5*0.2 +\frac{12}{6} = 0.1+2 = 2.1$

б)

$2\sqrt{\frac{9}{16}} -1 = 2\sqrt{(\frac{3}{4})^{2} } -1 = 2|\frac{3}{4}| -1 = \frac{11}{4} -1 = \frac{7}{4} = 1 \frac{3}{4}$
