BLM 3–12 Chapter 3 Test
1. D 2. C 3. D 4. A 5. D 6. 28
7. 1/8 8. –(4)^3, (–1)^5, 2^3, (–4)^2
9. a) 3 × 3 × 3 × 3 × 3 × 3 × 3
b) (–1) × (–6) × (–6) × (–6) × (–6) × (–6)
c) 4 × 4 × 4 × 5 × 5 × 5
10. a) 6^3 b) 7^4 c) 2^12
11. 11^3 means that a base of 11 is multiplied
3 times: 11^3 = 1331. 3^11 means that a base of 3
is multiplied 11 times: 3^11 = 177 147.
12. a) In the third line, Austin incorrectly distributed the exponent over subtraction to the bases of 1 and 0.05. You can only distribute an exponent over multiplication: (ab)^x = (a^x)(b^x).
I = 100(0.95)^3; I = 100(0.857375); I ≈ 86. The light intensity is approximately 86%.
b) When d = 15, I = 46%.
