Answer 1

Answer:

6. 3×(-1/2)³×(-1/2)^-1

= 3×(-2)³×(-2)

= 3×(-8)×(-2)

= 48

7. (-5/6)⁴÷ (-5/6)²×(-5/6)

= (25×25)/(36×36) ÷ 25/36 × (-5/6)

= (25×25)/(36×36) × 36/25 × (-5/6)

= 25/36 × (-5/6)

= -125/216

Also,

(-5/6)³

8. (1²+2²+3^-1)^-1

= (1+4+1/3)^-1

= (5 + 1/3)^-1

= (15/3+1/3)^-1

= (16/3)^-1

= 3/16

9. (2^0+3^-1+4^0)×5^-1

= (1+1/3+1)×1/5

= (3/3+1/3+3/3)×1/5

= 7/3×1/5

= 7/15

10. (6^-1 -7^-1)^-1

= (1/6-1/7)^-1

= (7/42-6/42)^-1

= (1/42)^-1

= 42
