Ответ:
[tex]\frac{18}{7}[/tex]
Объяснение:
[tex]\sqrt{3 \frac{6}{25} * 2 \frac{2}{49} } = \sqrt{\frac{81}{25} *\frac{100}{49} } = \sqrt{\frac{8100}{1225} } = \frac{90}{35} = \frac{18}{7}[/tex]
[tex]\displaystyle\bf\\\sqrt{3\frac{6}{25}\cdot 2\frac{2}{49} } =\sqrt{\frac{81}{25} \cdot \frac{100}{49} } =\sqrt{\frac{9^{2} \cdot 10^{2} }{5^{2} \cdot 7^{2} } } =\frac{9\cdot 10}{5\cdot 7} =\frac{18}{7} =2\frac{4}{7}[/tex]
