Answer 1

$\sqrt{1\dfrac{9}{16}\cdot0.0256} + 3 = \sqrt{\dfrac{25}{16}\cdot0.0256} + 3 = \sqrt{\dfrac{25\cdot0.0256}{16}} + 3 = \dfrac{\sqrt{25}\cdot\sqrt{0.0256}}{\sqrt{16}} + 3 = \dfrac{\sqrt{5^2}\cdot\sqrt{0.16^2}}{\sqrt{4^2}} + 3 = \dfrac{5\cdot0.16}{4} + 3 = 5\cdot{0.04} + 3 = 0.2 + 3 = 3.2$

Answer 2

Объяснение:

$\sqrt{1 \frac{9}{16} } \times 0.0256 + 3$

$\sqrt{ \frac{25}{16} } \times \frac{16}{625} + 3$

$\frac{5}{4} \times \frac{16}{625} + 3$

$\frac{4}{125} + 3$

$\frac{379}{125}$
