Question

( (85/6 . 83/2 ) / (810/6 ) )-1 : 3√ 0,008

Answer 1

( (85/6 . 83/2 ) / (810/6 ) ) -1 : 3√ 0,008 = 

= ( (7055/12) / (810/6 ) ) -1 : 3√(1/125)

=  ( 1411/324 ) -1 : 3√(1/5)² * 1/5

=  ( 1411/324 ) -1 : 3(√1/5)/5

=   ( 1411/324 ) - 1 * 5/(3√1/5)

=   ( 1411/324 ) - 5/(3√1/5)

≈ 3,354 - 5 * (3* 0,447) ≈ 3,354 - 5 * 1,341 ≈  3,354 - 6,708  

≈ 3,354
