Question

Which of the following shows the correct process of solving - 4 (3 + 12°) + 15° by generating an equivalent expression using the Zero Power Rule? (1 point)
- 4 (3 + 12º) + 15º = - 4 (15) + 15 = -60 + 15 = -45
- 1 (3 + 12º) + 15º = - 4 (15) + 1 = - 60 + 1 = -59
-1(3+12°) +15°=-1(3+1) +1=-1.4+1=-1.5=-20
-1 (3+12)+15º=-4(3+1)+1=-1.4+1=-16+1=-15

Answer 1

The fourth option. Using the Zero Power Rule (a^0 = 1):

-4(3 + 12^0) + 15^0 = -4(3 + 1) + 1 = -4·4 + 1 = -16 + 1 = -15.
