Step-by-step explanation:
hint: anthing with a 0 on top is always equal to 1
example: 3⁰ = 1, 4⁰ = 1
1 16⁰ = 1
2. 4^-2 = 8
3. 3⁻³= -3 x -3 x -3 = -27
4. 8⁻⁴ = -8 x -8 x -8 x -8 = 4,096
5. 1/ 2³ = 2³ = 8
6. 4/ ⁻³ = 2²/2⁻⁶ = 2⁸
7. 3 x 8⁰ = 3 x 1 = 3
8. 2 x 2⁻² = 2⁻¹ = 1/2 or 0.5 0r 2⁻¹
9. (-7)⁻² = 1/49
10. 9⁰ = 1
11. 2/2⁻¹ = 4
12. 8⁻²/ 80 = 2⁻⁶ or 1/64
13. 5 x 6⁰ = 5 because 6⁰ = 1 and 5 x 1 = 5
14. (-4.9)⁰ = 1
15. 7⁻²/7⁻¹ = 1/7 or 7⁻¹
16. x⁻⁸ = 1/ x⁸
17. xy⁻³ = X/y³
18. a⁻⁸b = b/a⁸
19. m²n⁻⁹ = m²/ n⁹
20. 1/x⁻⁷ = x⁷
21. 3/ a⁻⁴ = 3a⁴
22. 5/d⁻³ = 5d³
23. 6/ r-8s⁻¹ = 6s/ rs-8
24. 8a⁻³b²c⁻² = 8b²/a³c²
Answer: 110 miles
Answer:
304 IN
total inches needed for necklace : 38 x 5 = 190
total inches needed for necklace : 38 x 3 = 114
190 + 114 = 304 inches
The answer is x=9 so, its option 3.
