Ответ:
\(\sqrt{121\cdot64}=\sqrt{11^2\cdot8^2}=11\cdot8=88\).
\(0{,}25=\frac14\).
\(\sqrt{16\cdot\frac49\cdot\frac14}=\sqrt{\frac{16}{9}}=\frac43\).
\(\sqrt{27\cdot12}=\sqrt{324}=18\).
\(77\cdot24\cdot33\cdot14=(7\cdot11)(2^3\cdot3)(3\cdot11)(2\cdot7)=(2^2\cdot3\cdot7\cdot11)^2\).
\(\sqrt{77\cdot24\cdot33\cdot14}=2^2\cdot3\cdot7\cdot11=924\).
\(21\cdot65\cdot39\cdot35=(3\cdot7)(5\cdot13)(3\cdot13)(5\cdot7)=(3\cdot5\cdot7\cdot13)^2\).
\(\sqrt{21\cdot65\cdot39\cdot35}=3\cdot5\cdot7\cdot13=1365\).
