[tex]5²*2+7⁰-3³=25 \times 2 - 1 - 27 = 50 - 1 - 27 = 50 - 28 = 22 \\
[(1 1/4)²*4/5+3/12*2²]:(-1/3)²= (\frac{121}{16} \times \frac{4}{5} + \frac{3}{12} \times 4) \div \frac{1}{9} = ( \frac{121}{20} + 1) \div \frac{1}{9} = \frac{141}{20} \times 9 = \frac{1269}{25} = 63 \frac{9}{20} \\
\sqrt{ \sqrt{36 - \sqrt{25 = } } } = \sqrt{ \sqrt{36 - 5} } = \sqrt{ \sqrt{31} } = \sqrt[4]{31}
