1.
(1/3)⁻² + (1/7)⁻¹ + 6⁻¹
=> 3² + 7 + (1/6)
=> 9 + 7 + (1/6)
=> (16 * 6 + 1)/6
=> 97/6
2.
[(6/7)⁻² - (6/3)⁻²]⁻¹ ÷ (11)⁻¹
=> [(7/6)² - (3/6)²]⁻¹ ÷ (1/11)
=> [(49/36) - 9/4]⁻¹ ÷ (1/11)
=> (10/9) ÷ (1/11)
=> (99/10)
3.
[(1/2)²]³ * (1/3)⁻⁴ * 5⁻² * 1/9
=> (1/2)⁶ * (3)⁴ * (1/5²) * (1/9)
=> (3⁴)/(2⁶ * 5² * 3²)
=> 3²/2⁶ * 5²
=> 9/1600
6.
(8⁻² * 10⁻⁴)/(2⁻⁵ * 5⁻⁴ * 2⁻²)
=> (8⁻² * 10⁻⁴)/(2⁻⁷ * 5⁻⁴)
=> 8⁻² * 2³
=> 2⁻⁶⁺³
=> 2⁻³
=> 1/8
7.
[(2ⁿ⁺⁴) - 2 * 2ⁿ]/2 * 2ⁿ⁺³ + 2⁻³
=> (2ⁿ⁺⁴ - 2ⁿ⁺¹)/2 * 2ⁿ⁺³ + 2⁻³
=> (7.2ⁿ⁺¹)/2 * 2ⁿ⁺³ + 2⁻³
=> 7/2³ + 2⁻³
=> 7 + 1
=> 8
Hope this helps!
