Question

Evaluate when x = -19 10x - x - 17 + x / 16^3

Answer 1

10x - x - 17 + x/16^3

First simplify

10x - x = 9x

9x - 17 + x/16^3

16^3 = 16 x 16 x 16 = 4096

9x - 17 + x/4096

plug in -19 to the above expression


9x - 17 + x/4096

9(-19) - 17 + -19/4096

-171 - 17  - 19/4096

-188 - 19/4096 = 


- 188 - 0.00463867187 = -188.00463867187

-188.00463867187 should be your answer

hope this helps
