Answer:
6
Step-by-step explanation:
You can use Ruffini's rule to divide x^3 − 7x^2 − 18^x + 42 by x + 3 as follows
:
| 1 -7 -18 | 42
-3 | -3 30 | -36
--------------------------
| 1 -10 12 | 6
Then (x^3 − 7x^2 − 18^x + 42) : (x + 3) = (x^2 - 10x +12)*(x + 3) + 6
Look at the picture.
The remainder is 6.
