Answer 1

(-3)⁰÷(-3)⁷ =

( - 3 )⁰ - ⁷ =

( - 3 ) -⁷ =

$( - \frac{1}{3} ) {}^{7} =$

$( - \frac{1}{3} \times - \frac{1}{3} \times - \frac{1}{3} \times - \frac{1}{3} \times - \frac{1}{3} \times - \frac{1}{3} \times - \frac{1}{3} ) =$

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

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

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

$( \frac{1}{81} \times - \frac{1}{27} ) =$

$- \frac{1}{2187} = 0.00045$
