Answer the question circled and if you want to, the questions below

4^3 is 64 and 3^4 is 81. Therefore the answer to the circled question is -17.

1) 4^3 - 3^4 = 64 - 81 = (-17)

2) 34.782467:
to nearest decimal point: 34.7
to nearest 4 significant figures: 34.78

3) 2x + 4 / 18
    x = 4
   (2)(4) + 4 / 18
   (8) + 4 / 18
   12 / 18
   0.66 (was rounded to  nearest decimal place)
