To solve this expression, we can start by performing the operations within each set of parentheses.

First, let's multiply (-4,2+2,8) by (-1,5):
(-4,2+2,8) × (-1,5)

= (-4×-1, 2+2×5, 8×-1)

= (4, 2+10, -8)

= (4, 12, -8)

Next, let's add (-17,29-2,71) to the result:
(4, 12, -8) + (-17, 29-2, 71)

= (4-17, 12+29-2, -8+71)

= (-13, 39, 63)

Now, let's divide this result by (-2,5):
(-13, 39, 63) : (-2,5)

= (-13÷-2, 39÷5, 63÷-2)

= (6.5, 7.8, -31.5)

Therefore, the final result of the expression is (6.5, 7.8, -31.5).
