$3 {}^{0} + ( - 3) {}^{ - 2} + ( - 2) {}^{2} + ( - 1) {}^{2}$

Answer 1

${3}^{0} + ( - {3)}^{ - 2} + ( - {2)}^{2} + ( - {1)}^{2} \\ 1 + ( \frac{1}{ {3}^{2} } ) + 4 + 1 \\ 1 + \frac{1}{9} + 4 + 1 \\ 6 + \frac{1}{9}$

$\frac{6}{1} + \frac{1}{9} = \frac{54 + 1}{9} = \frac{55}{9}$
55/9=6,11111111111...
