Explicație pas cu pas:
a)
= 5/3+(-5⁵⁾/18⁽⁹*81⁽⁹/20⁽⁵)
=5/3 - 1/2*1/4
=⁸⁾5/3-³⁾1/8
= 40/24-3/24=37/24
-
b)
= 5/8+63⁽⁹/10⁽⁵ * ( -5⁽⁵/27⁽⁹)
=5/8-7/6=-13/24
-
c)
=45/28* (-16/27) -1/6
=5/7*4/3-1/6
=⁶⁾20/21-²¹⁾1/6= (120-21)/ 126= 99⁽³/126⁽³= 33/43
-
d)
=-28⁽⁴/15⁽⁵*(-12⁽⁴/5⁽⁵) -4/15
= (-7/3)*-(1/3)= ⁵⁾7/9-³⁾4/15
=35/45-12/45= 23/45
