510. Вычислите: C 211 1) 5) ТТ U 4 2 ; 2 2) 6) 9 2 3) 3 1 7) 2- 3 4. 3 4) 8) 3 3 1 ; 3​

Answer 1

$( \frac{1}{4})^{2} = \frac{1 ^{2} }{4^{2} } = \frac{1 \times 1}{4 \times 4} = \frac{1}{16}$

$( \frac{1}{9})^{3} = \frac{1^{3} } {9 ^{3} } = \frac{1 \times 1 \times 1}{9 \times 9 \times 9} = \frac{1}{729}$

$(1 \frac{1}{2})^{2} = ( \frac{3}{2}) ^{2} = \frac{3 \times 3}{2 \times 2} = \frac{9}{4}$

$(2 \frac{1}{3})^{3} = ( \frac{7}{3}) ^{3} = \frac{7 \times 7 \times 7}{3 \times 3 \times 3} = \frac{343}{27}$
