For Q3, you are doing great, you remembered that negative numbers can happen if the exponent is an odd number.
For Q4, I think you were confused with the fractions,
4(i)
![(\frac{2}{3} )^{4} = (\frac{2^{4}}{3^{4}}) = (\frac{16}{81}) =0.198](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B3%7D%20%29%5E%7B4%7D%20%3D%20%28%5Cfrac%7B2%5E%7B4%7D%7D%7B3%5E%7B4%7D%7D%29%20%3D%20%28%5Cfrac%7B16%7D%7B81%7D%29%20%3D0.198)
4(ii) is also wrong but I'll let you try to fix it yourself following what I given you for 4(i). You should get 1/64
Hope this helps!
