Maths (Indices (x⁻ʸ = 1/xʸ (4⁻² = 1/4² = 1/16), x⁵/³ = 3√x⁵ (EXAMPLE: 8⁵/³…

- - - - 8¹/³ would be 3√8 which = 2 so, now need to work out 2⁵ =2x2x2x2x2 = 32
      - work out 8⁵ = 32,768 then 3√32,768 = 32
  - - - 5+-3 = 5-3 = 2
        
        a²
  - - - 8-1/3 = 7⅔ = 23/3
        
        y²³/₃ or 3√y²³
- - - - Solution 2:
        We can also use a factor tree:
- - - - 3/5 ÷ 6/7
        = 3/5 × 7/6
        = 1/5 × 7/2 (the top 3 and bottom 6 cancel)
        = 1×7/5×2
        = 7/10
      - turn any mixed numbers into top-heavy fractions at the start. Then turn the fraction you are dividing by upside down, and multiply
