Answer 1

$0,3^{-3}+(\frac{3}{7} )^{-1}+(-0,5)^{-2} \cdot \frac{3}{4} +(-1)^{-8} \cdot 6 =\\ = (\frac{10}{3} )^3+\frac{7}{3} +4 \cdot \frac{3}{4} +6= \frac{1000}{27}+2\frac{1}{3}+3+6=37\frac{1}{27} +2\frac{9}{27} +9=48\frac{10}{27}$

Answer 2

0,3⁻³ + (3/7)⁻¹ + (-0,5)⁻² * 3/4 + (-1)⁻⁸ * 6 =

= 1/(0,3)³ +(7/3)¹ + 1/(-0,5)² * 3/4 + 1/(-1)⁸ * 6 =

= (10/3)³ + 7/3 + (-10/5)² * 3/4 + 1 * 6 =

= 1000/27 + 7/3 + 100/25 * 3/4 + 6 =

= 1000/27 + 63/27 + 3 + 6 =

= 1063/27 + 9 =

= 39 10/27 + 9 = 48 10/27
